Looking at the output you sent me from usbctl, it appears there is
in fact one device with two interfaces. Interface 0 is the mouse and
interface 1 is the keyboard. It looks like the uhid0 device is supposed
to be the instance related to the keyboard (interface 1) but it's
not seeing the HID descriptors. I'm not sure why this is. Possibly
the code that's setting up the uhid device instance isn't setting the
iface number correctly. If the interface setting was correct, you
should have gotten more information from usbhidctl on uhid1.
Unfortunatelt, I can't really debug this without physical access to
the device, and even then I'm not sure I can help since I'm not all that
familiar with the guts of the USB code. (You can try building with
USB_DEBUG and turning on some of the verbose logging to see where it
might be going wrong.)
