I would love if we did not have to build these quirks into kernel.
Given that majority of HID devices are compiled as modules, can we try
using request_firmware("<vid>-<pid>.descr") and try to load descriptor
overrides from disk before during device initialization? That would
also allow dropping bunch of trivial HID drivers that contain trivial
descriptor fixups.
Thanks.
