it will be a bit of a pain to debug this. the first thing you could
try is to rule out power issues... having the keyboard/mouse connected
to the raspberry pi 3 by a *POWRED* hub.

then for the actual debugging, connect the pi over serial... then
we can kill nusb/kb and rerun it manually with debug prints and
see where it diverges.

it colud be that for some reason we fail to fetch the hid descriptor,
and assume some default descriptor (boot protocol). or the device
fails to switch to from boot protocol to report protocol but we
interpret the data with the hid descriptor... (see setproto() in
/sys/src/cmd/nusb/kb/kb.c)
