Blacklisting a usbhid device

[Rick L. Vinyard, Jr.]

I'm trying to write a driver for the Logitech G13 keypad, but one of the
first problems I'm running into is the usbhid driver claiming the device.

I'm working on a Fedora 11 system, so I checked the usbhid driver and it
is built in.

I applied the following patch and rebuilt the kernel, but usbhid still
claims the device. Another problem I noticed was that I received a compile
error when I used HID_QUIRK_IGNORE rather than 0x00000004.

Is it not possible to blacklist a device without compiling usbhid as a
module?

Also below is the output of lsusb -vvv for the G13.

Any suggestions on how to either work within the usbhid framework or how
to get usbhid to stop claiming the device?

Thanks,

Rick
