>Description:
The I-Tuner Networks USBLCD4X20 is a bus-powered external USB 4x20 LCD display.
When plugged in, uhid attaches to this device, rendering it useless. The
attached patch adds the proper quirk so that uhid doesn't attach to it. This
allows software such as LCDproc to talk to it and display useful information.
>How-To-Repeat:
Plug the device in, and try to use any libusb-based application to talk to the
device. They will fail to claim the appropriate interface.
>Fix:
See attached patch.
