Hi Bradley,
first, it seems that the patch is actually doing quite the reverse of what
you wanted to do, right? (it's removing lines that have never been in
kernel).
Second, what are the specific drivers? Are they going to be posted for
upstream kernel inclusion?
How does the device behave with USB HID driver? It doesn't work at all, or
it's just that it only providing basic HID capabilities without any
vendor-specific extensions?
Thanks,
