i have the same problem but with another usb device:

Bus 005 Device 002: ID 147a:e02c Formosa Industrial Computing, Inc. Infrared Receiver

it is a infrared receiver but in fact is like a usb keyboard.

my laptop is an old Acer Aspire 5510 and i never was able to make my infrared get working but i read this thread and now i could fix the problem..

quoting to this guy....

#define HID_MAX_USAGES 12288

from 12288 to a value greater than 32k,
recompile and install the new kernel.

i did this and now its working:
