Hi @Arti3DPlayer

Could you help me how to send USB bulk transfer requests?

Thanks so much!

we are getting a lot of strings leaking from running monitor just for a few seconds:

leaks Report Version: 4.0
Process 57082: 153864 nodes malloced for 26207 KB
Process 57082: 1036 leaks for 52400 total leaked bytes.
999 (49.9K) ROOT LEAK: CFString

memory graph helped to find the location:

https://github.com/risc604/USBDeviceSwift/blob/4f9ce757a1ac6c479c3114e6043d5d4d65458c29/Sources/SerialDeviceMonitor.swift#L31

to fix we used:
return propValue?.takeRetainedValue()

same issue as in risc604/USBDeviceSwift#1

I believe there is a slight bug on lines 20-21 in the ViewController here...
https://github.com/Arti3DPlayer/USBDeviceSwift/blob/master/CleanFlightSerialExample/CleanFlightSerialExample/ViewController.swift#L20-L21

Instead I think it should be

if (self.devices.count > 0 && self.devicesComboBox.indexOfSelectedItem > -1) {
                let device = self.devices[self.devicesComboBox.indexOfSelectedItem]

I'm new to Swift (and IOKit), so there may be a better way to do this.

I have just come into contact with Swift and MacOS technology, and I need to develop a software for keyboard communication. Several problems about HID、USB communication bothered me for many days until I found your project. Please allow me to express my sincerest thanks. Thank you very much.

This is more of a request for help than an actual issue, but I feel like I'm fairly lost at this point.

I'm essentially trying to figure out how to port something like this, to USBDeviceSwift/IOKit.

As you can see from the protocol link above, the requests are fairly straightforward to construct (apart from wLenDone, which I'm still confused about), but the main issue I have is how I'd handle the way PyUSB provides a write function, as the first parameter is always referred to as an endpoint, which does not sound like a request type etc.

To make things more confusing, I don't actually have a Kraken X61, but an X62, which has an entirely different protocol. That said, I'm trying to at least replicate the logic here, which is specifically for the X62, but notice how there is no request logic there at all, only write calls, so I'm stumped trying to find a way to write byte data to a specific "endpoint", using USBDeviceSwift.

Every bit of information to help me along would be massively appreciated!

Hi Arti,

Do you plan to add support for getting already connected USB/HID devices?

Thanks,
Graham

Hi, is it possible to get the BSD Path of a mounted USB device by using / adapting this code? I've researched various interconnected stackoverflow responses:

https://stackoverflow.com/questions/40008280/usb-device-path-in-swift/46319129#46319129
https://stackoverflow.com/questions/39003986/usb-connection-delegate-on-swift/39026607#39026607
https://stackoverflow.com/questions/34628464/how-to-implement-ioservicematchingcallback-in-swift/39662693

Some posts mention BSD path. I can't see a straightforward kUSB key for it, to add it.

Currently, app gets the path by associating it with a mount notification - but that fails when a device is already connected when the app launches.

Having access to the BSD path / mount path in USBDevice would be super useful?

Thanks,

Ian Grant

First, Thanks to the good repo.
I use the demo to send a command to USB device.
But the kr is -536854449.
`func getStatus() throws -> [UInt8] {
//Getting device interface from our pointer
guard let deviceInterface = self.deviceInfo.deviceInterfacePtrPtr?.pointee?.pointee else {
throw STM32DeviceError.DeviceInterfaceNotFound
}

    var kr:Int32 = 0
    let length:Int = 2
    var requestPtr:[UInt8] = [UInt8](repeating: 0, count: length)
    // Creating request
    var request = IOUSBDevRequest(bmRequestType: 161,
                                  bRequest: STM32REQUEST.DNLOAD.rawValue,
                                  wValue: 0,
                                  wIndex: 0,
                                  wLength: UInt16(length),
                                  pData: &requestPtr,
                                  wLenDone: 255)
    
    kr = deviceInterface.DeviceRequest(self.deviceInfo.deviceInterfacePtrPtr, &request)
    
    if (kr != kIOReturnSuccess) {
        throw STM32DeviceError.RequestError(desc: "Get device status request error: \(kr)")
    }
    
    return requestPtr
}`

Hi,

I am trying to send some data to a mouse using the RFControllerHIDExample. I can connect to the device and I can enter some data that the application will send. However, it isn't clear for me what data the application sends. I know how to do this in C# and I have some working hexcode that controls the light in the mouse, but when I paste that piece of code or the conversion of that hexcode in the field to send it to the mouse, nothing really happens. Do I need to send some data in a selected format, or can I use whatever I want? What kind of data does the application expect from me?
Thanks in advance,
Harmen

When I try to install this swift package I get the following response:

$ swift build
Updating https://github.com/Arti3DPlayer/USBDeviceSwift.git
error: dependency graph is unresolvable; found these conflicting requirements:

Dependencies: 
    https://github.com/Arti3DPlayer/USBDeviceSwift.git @ 1.0.3..<2.0.0

My package file looks like this:

// swift-tools-version:4.2
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "WiredMouse",
    dependencies: [
        .package(url: "https://github.com/Arti3DPlayer/USBDeviceSwift.git", .upToNextMajor(from: "1.0.3")),
    ]
)```

when I, instead of "1.0.3", set the version to "2.0.0" I get the same result but one step higher: 
```shell
$ swift build
Updating https://github.com/Arti3DPlayer/USBDeviceSwift.git
error: dependency graph is unresolvable; found these conflicting requirements:

Dependencies: 
    https://github.com/Arti3DPlayer/USBDeviceSwift.git @ 2.0.0..<3.0.0

And so on

Can somebody please help me get forward? I'm new to swift package manager so I don't know a lot about it.

Thanks

Hi there,

First of all, I would like to thank you for your effort to create this library. This is absolutely helpful!

I just want to ask for your support as I don't have idea how to send this command to a USB device:

Reboot command: 0xdf 0x40

I need your help on this. Thanks so much!

Hi, can you think of any reason why I can receive the disconnection notification but not the connected notification?

There's no errors whatsoever, I simply don't get the connected notification. I've tried a few different usb devices and all the same.

Using Swift 4 in High Sierra.

Hello,

We are facing some issue with the write command, as we have a Report Size 9 Byte and we are using a Byte array instead of String.

We are getting response code 0, can you please clarify the meaning of this response code?

What we require is 9 Byte in Response of write command.

Please try to help us ASAP.

THANKS!!

Hi, to keep code compatibility, please include a proper release tag in the repo.

This allows for Swift Package Manager to use the .upToNextMajor(from: "0.1.0") and related version compatibility methods.

Hi,

loving the code. I have a question about how it can be modified to handle multiple connections of the same device.

Let's say I have two USB Mice, both are made by the same manufacturer, so both have the same vendor id and product id. When a button on mouse 1 is pressed I want to print "Hello", and when a button on the other mouse is pressed I want to print "World".

The read function receives all the data from the press of a mouse button, but I can't work out how to tie this back to a device that was detected in the rawDeviceAdded function.

It there anyway of doing this?

Thanks

Hello,

Can you please help me make same request using IOUSBDevRequest as if I was using PyUSB write function? I don't know if you are familiar with PyUSB but It has very simple api just dev.write('hello') and automatically calculates bmRequestType, bmRequest do you think this library could have same api or can you tell me how should I go about setting bmRequestType and bmRequest?

I know very little about USB so I don't know if it is even possible

Thanks for great repo!

Our device is a USB Mass Storage and only accepts SCSI command. That said, does this library supports SCSI command set? If so, is it the same way on your example? If not, could you please give me idea on how to do it?

https://github.com/Arti3DPlayer/USBDeviceSwift/blob/master/STM32DeviceExample/STM32DeviceExample/STM32Device.swift#L46

Thanks so much for your assistance!

Hi @Arti3DPlayer,

It seems that support for HID device communication isn't included in the Cocoa Pods USBDeviceSwift package. Looking in my Pods folder, I can see the USBDevice struct and the USBDeviceMonitor class, but I don't see the HIDDevice struct or HIDDeviceMonitor class or the others referenced in your examples and documentation. When trying to follow the HID example from your documentation, I receive unresolved identifier errors.

The target “USBDeviceSwift” contains source code developed with Swift 2.x. Xcode 9 does not support building or migrating Swift 2.x targets.

Use Xcode 8.x to migrate the code to Swift 3.

Has the pod just not been updated?

Is it possible to disable/enable a device with your codebase? We have actors being filmed using laptops, and need to prevent them from actually typing or using the trackpad, but keep an external mouse/keyboard active.

Alternatively, intercepting and disposing of any events from the devices would be usable as well. Would this codebase be suitable for that?
