Just recently my Tomoko keyboard stopped working with Ubuntu 16.04. It only happens after waking the PC from suspend. The mouse works fine but the keyboard does not. I have to unplug it and plug it back in before its starts working again. Does anyone have any ideas how to trouble shoot this? I looked in dmesg but not really sure what to look for.
I see this "failure" after plugging the Tomoko keyboard back in but unsure if its related to the hang after waking from suspend? It also works despite this error (hid-generic 0003:04D9:A0CD.000B: usb_submit_urb(ctrl) failed: -1)

The odd thing is after the PC is suspended I can use the Tomoko keyboard (tap space bar) to wake the PC, but after that the keyboard no longer works. I have to unplug it and plug back in.
Looking in dmesg I believe this is what I get after trying to wake after suspend:
[10171.636787] hid-generic 0003:04D9:A0CD.000B: usb_submit_urb(ctrl) failed: -19
I was able to fix the problem by adding
usbhid.quirks=0x04D9:0xA0CD:0x20000408to kernel boot parameters as described here https://unix.stackexchange.com/a/280574/41667.
