The device which identifies itself as a "USB Keykoard" (no typo) with 
VID:PID 1a2c:0023 does not seem to be handling the reports initialization 
very well. This results in a "usb_submit_urb(ctrl) failed: -1" message 
from the kernel when connected, and a delay before its initialization. 
This patch adds the quirk for this device, which causes the delay to 
disappear.
