The Acer branded keyboard that came with my Acer ATC-605-UB11 computer system
fails to see any keystrokes due to:
85455dd906d5 ("HID: redragon: Fix modifier keys for Redragon Asura Keyboard.")
That commit is in 4.18.0-rc4.
The vendor_id device_id combination 0c45:760b is shared by those keyboards, as
well as many others. See https://linux-hardware.org/index.php?id=usb:0c45-760b.
While the Redragon keyboard uses the second device presented and not the first,
the Acer, and perhaps many others, use that first device
(with dev->maxapplication==1). hid-redragon.c driver should not cause this
device to be ignored. It appears to me that this problematic change was made
late in the commits patch set as a clean up.
As there are many different devices being intercepted by the new hid-redragon
driver, and as the bytes x81 x00 are not rare in this context, I also think it's
advisable to improve the verification condition before performing the
report-description patch only meant for the Redragon Asura Keyboard.
These two patches will follow. The first restores the function of my keyboard
sucessfully.
I don't have the Redragon Asura Keyboard necessary to test the second patch and
it shouldn't be merged until it can be tested by someone who does.
