   I haven't managed to duplicate this as we're running the code on a Raspberry Pi and Windows, and I've only tested on an older Mac. I did come across this thread that seemed related:

   If you drop pyusb and libusb and use hidapi this works perfect.

   Just install hidapi: pip install hidapi

   And replace pyusb references with:

   import hid
   
   hidraw = hid.device(0x2123, 0x1010)
   hidraw.open(0x2123, 0x1010)
   hidraw.send_feature_report([0x02, 0x10, 0x00,0x00,0x00,0x00,0x00,0x00])
   

   The above code will connect to the device and send a fire command.
