Esp32s2 is full speed mode only, so variable _bcdUSB on EspTinyUSB constructor must be 0x0110

Hi

I have seen that you have added SD Mass Storage

I tried to test this but when I compile the example your library gives many errors.

Now I can't use the keyboard example either

I attach screenshots with the errors:

Thanks

After successful uploading of this sketch: EspTinyUSB-master\examples\hid\gamepad\gamepad.ino
the USB-device is successfully installed and appears in Control panel.
And it looks like working properly (axes and buttons change their values).

But, in terminal program, via COM-port, it says this (with an interval of 1 sec.):

The other sketches in folder "EspTinyUSB-master\examples\hid" (like keyboard.ino and mouse.ino) work properly without any errors in terminal window.

With the latest repo of Arduino ESP32 (idf/release 4.2) it gets stuck after clicking the upload button with the indication "connecting..." After a while it times out, and the process gets unsuccessful.

I'm using ESP32-S2-Saola with native USB pins, there is no UART converter.

Hi chegewara,

How can I flash a bootloader that could work with Arduino Ide or Platformio?

Im stucked. Thank you.

I'm using the Arduino IDE with V2.0.1-RC1 boards installed with the boards manager.

I lost my OTA because of this so I can't try anything for the next couple of hours :(

Any ideas?

Thanks for this excellent work!

Will it be possible to support USB Host functionality on the S2? Is this something that's being developed?

mscusb.cpp is ok, but flashdisk.cpp, ramdisk.cpp, and sdcard.cpp throw compile errors
when CFG_TUD_MSC is set to 0 in
hardware/espressif/esp32/tools/sdk/esp32s2/include/arduino_tinyusb/include/tusb_config.h

with Arduino 1.8.16

Hello.

I would like to contribute to this effort as I have a bunch of old 128 / 256 / 512MB generic USB flash sticks that I want to host files on via ESP32-S2. Ideal aim is to then load images from a USB stick onto say a massive LED Panel Display :-)

... but I don't understand how exactly to wire these up to the ESP32-S2 or S3. Can you please provide a diagram?

Hi!

I'm using a lilygo esp32_s2_woor. I was able to run most of the examples provided but the msc one.
It compiles but when I connect the module to my PC nothing happens...

I also made an attempt defining this:

#define CFG_EXAMPLE_MSC_READONLY

but it didn't solve. Was anyone able to run this example?
Thanks!

Tried to compile example file keyboard2.ino for M5Stack-ATOM, file tusb.h seems to be missing?
The following is the error message from the Arduino IDE:

For context, this is my platformio file:

The project does however not compile as I get this error:

Do I need to include something else to get it to compile out of the box?
After removing sdusb.h and sdcard.cpp, the project compiles.

Next problem that I have is the inability to get webusb to work.
This is my sketch:

#include <Arduino.h>
#include <Wire.h>
#include <SPI.h>
#include <webusb.h>
#include <cdcusb.h>

WebUSB WebUSBSerial;
CDCusb USBSerial;

class MyWebUSBCallbacks : public WebUSBCallbacks{
    void onConnect(bool state) {
      USBSerial.printf("webusb is %s\n", state ? "connected":"disconnected");
    }
};

void setup() {  
  while (!Serial);

  WebUSBSerial.landingPageURI("localhost:3001", false); // even if set to default URL, does not show up
  WebUSBSerial.deviceID(0xcafe, 0x0002);
  WebUSBSerial.setCallbacks(new MyWebUSBCallbacks());

  if(!WebUSBSerial.begin()) {
    USBSerial.println("Failed to start webUSB stack"); // does not fail - checked
  }

  if(!USBSerial.begin()) {
    USBSerial.println("Failed to start USB stack"); // does not fail - checked
  }
}

void echo_all(char c)
{
    Serial.write(c);
    WebUSBSerial.write(c);
    USBSerial.write(c);
}

void loop() {
  
  while (WebUSBSerial.available()) {
      echo_all(WebUSBSerial.read());
  }

  while (Serial.available()) {
      echo_all(Serial.read());
  }

  while (USBSerial.available()) {
      echo_all(USBSerial.read());
  }
}

The CDC class device works and the messages are echoed to my serial monitor console successfully via my computer terminal with
xtrinch@elizabeta:~$ echo -e "test" > /dev/ttyACM0.
I can even flash the device via this tty and do not have to enter bootloader mode.

The problem however is the web usb, as the device does not show up in chrome under available devices. Note that I've tried without any vendor filters and the device is just not here. Neither does it have a designator in /dev/tty* (Not sure if the web usb devices should have that though?). If I boot the board in bootloader mode, it shows up in chrome as an espressif device, so it's definitely a software thing.

I've tried also with the default www.tinyusb.org/examples/webusb-serial by omitting the custom URL specifications but it does not show up there either.

I am using latest chrome on ubuntu 20.04.

Please help.

While it's perfectly doable to put the board in bootloader mode and then flash, it would be really great to be able to flash it without that, like any other esp32 boards. The board isn't in sleep mode or anything, and I can even talk to it via webusb, but I can't flash it.

I'm getting this error:

Any ideas? Any help would be greatly appreciated, even if only to point me in the direction of what this error is and where do I start looking.

In VSCode Platforio, and also in Arduino IDE, the compile throws countless of lines of warnings. The are all about redefinition. I know warning is not an error, it works, but maybe it worth noting them. Because warnings usually help avoiding future errors. Some examples while compiling gamepad.ino:

Hi,

where are defined the costants like HID_KEY_A used in example keyboard.ino?

Whenever I try to run any of the examples I get the following errors:

EspTinyUSB-master/src/classes/msc/sdcard.cpp:66:12: error: 'class fs::SDFS' has no member named 'readRAW'
SD.readRAW((uint8_t*)buffer, lba);

And then a similar one but for 'writeRAW'

Dear all,

With all the recommended fixes, I can get the samples to work, except the gamepad. It shows up, but the sample code does not work.

I am using 2.0.0-rc1 and the master.

Best,
X

We have now added persist reset in CDC, which allows arduino IDE to enter bootload mode without need to press buttons, just like with UART.
There is one small issue, which i probably not fix, but worth to mention. It is required to press upload button twice, first time to enter bootloader mode and again to start flashing. The issue is caused by 2 probably things:

• my lack of knowledge about this mechanism,
• library design, which i prefer to stay this way.

To make it work with 1 time button press it is required the CDC descriptor to be exactly the same as in ESP32 S2 bootroom, which is using EP addressing i dont really like (3, 84, 85). We have not too many EP available on S2 and i prefer to have EP addresses with consecutive numbers, which makes it easier to handle and to use few classes at the same time.

Hi,

Thank you for the library!

I've got it up and running well and have run some of the examples. I'd like to use it as the basis for an adaptor to use other controllers on an original Xbox but can't work out how to apply a specific set of descriptors to the format/structure used by the library.

The descriptors can be found here but there don't seem to be completely analogous sets of descriptors across the projects.

Can you offer any guidance? I was wondering if the right approach is to subclass HIDgamepad or HIDusb to return these fixed descriptors, rather than generating them as seems (I think?) to take place in ESPTinyUSB::begin(...)?

Any help would be much appreciated! As is probably obvious, I'm still relatively new to C++.

Thanks.

I'm trying the example from examples/host/msc/msc.ino. Read & write function is working normally, but it crashed when removing the flash drive. The ESP print this error:

Rebooting...

I'm using AI-Thinker dev module ESP-12K with 8MB PSRAM.
Any idea why this happen? Do I need to do something before removing the device? Or maybe I need extra component? I'm connecting female USB port directly to pin 19, 20, VCC and GND.

Hi,

I have a rather strange problem with my webusb + CDC setup. Below are the usb descriptors generated with this library.

The web usb part is working without issues on Linux (Ubuntu 20.04), I can connect to it, send it characters, receive characters, the whole thing. On windows however, I can see it in chrome and can connect to it, but cannot claim the webusb interface. (Note that I am testing with the same website on linux/windows). Below is the code I am using. I'd be inclined to think I'm doing something wrong in javascript, if the exact same code wasn't working fine on Linux. I even tested with the nightly build of chrome to see if it is some random chrome bug. The code just stalls at claimInterface and never returns. No errors, just never returns.

What could possibly be the cause of this?

Javascript code:

can't get debug descriptor: Resource temporarily unavailable
Device Status:     0x0000
  (Bus Powered)

I'm sure I'm doing something wrong here, but now I've got everything building successfully (thanks for the pointer chegewara), I now cant get the ESP to initialise as a USB device properly.

For example, using the keyboard2.ino example (or any other example from this library I've tried), Windows shows this error in device manager:

And with Core Debug=Verbose on the ESP, I get the following lines logged from via UART0:

13:55:02.704 -> [  1248][D][hidkeyboard.cpp:23] begin(): begin len: 25
13:55:02.737 -> [  1248][D][usb_descriptors.cpp:45] getConfigurationDescriptor(): descriptor length: 34
13:55:02.737 -> 
13:55:02.737 -> [  1250][W][esptinyusb.cpp:185] begin(): failed to init, (return fixed in tinyusb 0.8.0)
13:55:02.737 -> [  1258][D][esptinyusb.cpp:47] esptinyusbtask(): USB tud_task created
13:55:04.746 -> FAIL
13:55:05.720 -> FAIL
13:55:07.726 -> FAIL

So it looks like the usb begin() is failing, but I cannot see why.

I've tried the same setup using PlatformIO and Arduino IDE and have the same results.

I'm able to successfully compile and run the USBSerial example from ESP32 Arduino, which gives the expected results on the USB interface. I believe this rules out possibilities that I have some kind of hardware problems...maybe? I can also upload sketches to the board using CDC so that also gives me confidence in the hardware.

A few other points about my environment, in case it is of relevance:

• Windows 10
• Board is Lilygo TTGo T8 ESP32S2. Also tried and same issue with Lilygo TTGO ESP32S2 V1.1

Please can anyone help? Any pointers would be very greatly appreciated.

I am trying to fix now all breaking changes introduced in upstream tinyusb library and i found there is some issue which i cant fix.
As you all know the core repository for all espressif boards is https://github.com/espressif/arduino-esp32. Maintainers of that repository also are making tinyusb library built-in as a core library and with most recent they did i think i am not able to "fix" my library to let it run alongside core-tinyusb. Here is error log i am having now:

The problem is any of those upstream callbacks cant be overridden.
Maybe there is some way to fix it all, but i spent few hours and endup in deep hole and without changes in arduino-esp32 i dont see option to continue developing this library.

Each class should have its own set of callbacks. It will be easier to handle callbacks from object level if eventually will be possible to have 2 or more instances of the same class like 2x CDC or HID.

I need to have both mouse and keyboard working from one esp32-s2. So i tried this code but in device manager of windows does not recognize the device.
NT: i tried both seperately and they work fine.

What am I doing wrong?

My version of arduino-esp32 is 2.00-alpha. I hope that isnt the cause of the problem?
Thank You.

I am thinking about refactoring some functions to return bool value to signal if function succeeded or not, for example hid functions.

Any thoughts?

Hi,

Thanks a lot for you project. And I want to try it under Arduino environment.

First I install your library then copy the source code of tinyusb to the source directory.

But I still get below error message:

Documents\Arduino\libraries\EspTinyUSB-master\src/osal/osal_freertos.h:32:20: fatal error: semphr.h: No such file or directory

Could you please with a simple guide of how to use your library?

Z.t

Hello, I'm trying to include this library to my Arduino IDE, without success.

So I tried download the TinyUSB (https://github.com/hathach/tinyusb) and merge the src folder, but still getting erros.

Could you teach me the steps to make it work ?

tinyUSB don't have some symbols accessible directly. In order to get $%^&?" and other symbols i used this method but can get it working. if i press the keys i get only numbers.
What the issue might be?

I am trying to use the MODIFIER keys from this list, but it does not work. I get no output. see the processKeys function, i tried both commented and un-commented one. Commented one also does not work also it only gives output from some keys fromthe array. but un-commented one, every key works except the HID_KEY_CONTROL_LEFT.

Hi, I know this question already got raised but just pointing out that the flash that ESP32 modules are equipped with would be great to access through this library.
The Ramdisk option - just too little space for practical value.
The SD card option - great but requires additional hardware.

If anyone have time, a "flash_msc" would be just great. Perhaps using the LittleFS filesystem :). What do you think.

For some reason, Windows is not seeing a HIDGeneric device unless I put a large (50-100ms) delay() in my loop. Occasionally it will enumerate and immediately disconnect, or simply not be visible at all. This is with an ESP32-S2 feather,

Obviously one of the advantages of HID is the data rate, so this does seem counterproductive.

Hi, I have a question about hidkeyboard lib

When I wrote the demo code for my keyboard. I got the crash message and my esp32-s2 always reboot.

This is my code：

#include "hidkeyboard.h"

HIDkeyboard dev;

void setup()
{
    Serial.begin(115200);
    dev.begin();
    dev.sendPress(HID_KEY_A, 0);
    //delay(1000);
    //dev.sendRelease();
    
}

void loop()
{
    delay(1000);
    Serial.println("loop...");
}

And the this is the esp32 log:

The sendChar work for me. I do not know how to debug.

Hi!
I have try to test usb host function on new esp32-s2 but the compile failed pointed toward "usb/usb_host.h: No such file or directory"
Where I could find that file?

Thanks

I want to make a USB Stick Writeblocker.

Is it possible to plug a USB-Stick to ESP32-S2 and emulate a USB device with the content of the actual USB-Stick to make it read only?

can you support CDC ECM/RNDIS ?

Hi, @chegewara, I'm trying to use an ESP32S2 USB stick(https://www.hackster.io/news/create-custom-usb-devices-with-the-esp32s2stick-458bf370a522) to make an SD to USB adapter, however it seems to be taking too long to read the whole 8GB SD card for the USB, when I enable verbose core debug level, it just shows "[V][sdcard.cpp:65] onRead(): default onread". I saw on this post: https://www.esp32.com/viewtopic.php?t=15908 that you used a 16GB SD card and got it working. The comunication with the SD card is working, because the test code created the directory /mydir, wrote and read the hello.txt file, so to me it seems like something on the USB side.

My code is this:
USB_stick.zip

Obs.: I tried putting the code in the post, but I couldn't get right, this is my first post on github.

I'm using ESP32 2.0.1 RC1 and windows 10.

Edit: I tested it on linux and it worked, but on any windows machine it seems to not work.

This is actually a feature request, but i couldn't figure out how to tag it as such.

Many SD BO and connectors support a much faster SDIO compared to the legacy SPI. This would significantly alleviate the speed bottleneck which is at least partially caused by the SPI interface in the example. This might even be relatively simple to implement, as esp32 s2 supports SDIO, and the arduino-esp32 library has provided SD_MMC API in their examples, The API format is relatively similar to the SPI API, the only seemingly significant difference being the amount of pin connections needed.

There is issue with unmout msc device. When device is unmounted from system, but onReady will return true, then tinyusb stack will call onunmout all the time:
https://github.com/chegewara/EspTinyUSB/blob/master/src/classes/msc/ramdisk.cpp#L32

We need to think how to implement this:

• add class USBCallbacks in each MSC class (ramdisk, sdcard etc), or
• let the user to implement it in own code.
• implement it in each class and allow user to add its own USBCallbacks, to allow actions in mount/unmount

Pros/cons:

• 1st option - simplify library use, dont bother user with low level actions, but wont let him to add led blinking depending on device state,
• 2nd option - more flexibility, but also more complexity for user,
• 3rd option is best, because will handle onready for user, and allow to add led blinking or similar things depending if device is mounted

When I try the MIDI example, it builds and runs ok, but I dont see the MIDI device on my system. Running lsusb -v shows that the Espressif Device is there and has some MIDI properties, but no program that uses MIDI cannot see or use it. I tried it in Windows and Linux.

I had this working great in July or so.
I went back to revisit it and won't compile (Webusb example) due to usbd.h file missing.
Also errors related to usb endpoints.
Any help is appreciated.
Thanks!

Is there also Media Key support (planned)?

e.g., KEY_MEDIA_NEXT_TRACK , KEY_MEDIA_PLAY_PAUSE, KEY_MEDIA_VOLUME_UP ...

Best regards

Thank you for your library, how to expose the onboard external flash memory as USB Mass Storage?

This issue is in reference to the "all_in_one" example - I have not tried any of the others.

The code is compiling, I have the ESP32S2 branch installed (manually) in the Arduino IDE, I can build and download the code, but all it does is what is shown in the log below.

Is there any particular setup option and / or partition scheme I have to use to make this work?

I want to send the power related info of m device's battery using the esp32's usb. i come to know of a protocol that used by the UPS which communicate using a usb cable attached to the computer.

there is a library that works with Arduino pro micro, this one https://github.com/abratchik/HIDPowerDevice

is there any possibility if you can add support for it?
