Well, you can always unbind interface 0 from usbhid -- it corresponds
to the 2-1.1:1.0 file in /sys/bus/usb/drivers/usbhid/. If you do that,
you'll probably find the few keys which _do_ currently work suddenly
stop working.

But there's nothing to be done immediately about interface 1; usbhid is
_already_ using it. It just isn't using it correctly.

Adi,

could you please provide output of

cat /syse/kernel/debug/hid/<keyboard>/rdesc

anytime after the keyboard has been plugged, and

in /sys/kernel/debug/hid I have two devices for the keyboard. One is 0003:060B:0230.0002 and the other 0003:060B:0230.0003

attached are the rdesc files for both devices.

cat /syse/kernel/debug/hid/<keyboard>/events

I only get events for the working keys on the *:0002 device.
All other files were empty after I pressed some keys.

The events for the working keys are attached in the *.events file.
I first pressed backspace and then the menu key.

Cheers
Adi
