Comment on Linux permissions

First of all, really cool project, congrats!

One thing about the permissions on Linux. The documentation says:

Note that by default on Linux, the USB port can only be used by root. Unless you change the device's permissions, you will need to sudo to execute the binary.

While sudo might be ok for a quick hack, the best way is to install some udev rules to give permissions to use the Push2 from any user (or some specific user if prefered). The easiest way to do this is to add a a file /etc/udev/rules.d/50-push2.rules with the following contents:

SUBSYSTEM=="usb", ATTR{idVendor}=="2982", ATTR{idProduct}=="1967", GROUP="plugdev"

This will make sure that Push is writable by any user that is in the plugdev group (normal users are usually there). To make the rule effective one can simply reboot or otherwise:

sudo udevadm control --reload-rules
sudo udevadm trigger

Maybe there could be a make install provided that does something like this or otherwise a pointer in the README so users do this themselves.

Cheers!

Could not claim device with interface 0, error -99

Hi,

I was trying to compile and run the push2 display example on OSX 10.13.6, but I'm getting this error when the application is trying to claim the interface: Could not claim device with interface 0, error -99.

Stepping through the code in the Xcode debugger, it fails in darwin_usb.c:1327

  /* Do the actual claim */
  kresult = (*plugInInterface)->QueryInterface(plugInInterface,
                                               CFUUIDGetUUIDBytes(kIOUSBInterfaceInterfaceID),
                                               (LPVOID)&cInterface->interface);

kresult is -2147483644. In Apples developer forums I found:

IOCFPlugInInterface's QueryInterface returns an error, HRESULT = -2147483644.
...
That error translates to 0x80000004, which is defined in <CoreFoundation/CFPlugInCOM.h> as E_NOINTERFACE

https://forums.developer.apple.com/thread/110920)

Any idea what could be causing this?

Thanks
