All information I  managed to extract by using usbhidctl is below:

# usbhidctl -f /dev/uhid1 -ra
Report descriptor:
Collection page=Consumer usage=Consumer_Control
Input   size=8 count=1 page=Consumer usage=Eject, logical range 0..255
End collection
Total   input size 1 bytes
Total  output size 0 bytes
Total feature size 0 bytes
usbhidctl: USB_SET_IMMED: Device not configured

If it is not enough, will you explain to me how to use this utility?

Thanks!
