Description David Demelier 2017-11-06 07:56:41 UTC

I have a Lenovo Professional Keyboard combo which is not working on Linux because it sends an extra byte (0x71) for each key.

Some people explains the situation in the followings links:



Do you think it's possible to make usb keyboard driver able to understand this extra byte?

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.

I have installed Kernel 4.16.6-302.fc28.x86_64 (Fedora) and 4.15.0-20 (Uubntu) and the keyboard still doesn't work. Is ts possible to fixed it?

Keyboard is sending extra byte with each key-press, as temporary workaaround you can use mapping in this repository (tested on Fedora 28 with 4.20 kernel)
