Hello,

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.

Bug description:
Hi
I got an issue on Ubuntu 18.04 with latest packages.
uname -a:
Linux MyLaptop 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

lshw:

                   description: Keyboard
                   product: Lenovo USB Receiver
                   vendor: Lenovo
                   physical id: 3
                   bus info: usb@1:3
                   version: 1.05
                   capabilities: usb-2.00
                   configuration: driver=usbhid maxpower=100mA speed=12Mbit/s

My wireless keyboard is not working, Ubuntu only recognize some
special keys (Super, Ctrl, Shift, Alt)

This is a Mouse+Keyboard combo using a wireless receiver by usb:

lsusb:
Bus 001 Device 005: ID 17ef:609b Lenovo

Mouse works fine, and in Windows 10 it works with no issues.

I found multiple reported problems with this keyboard in other distros (and from Asus too, as the real manufacturer is Primax Electronics).

There is a workaround (I still didn't tried) but it needs to compile an specific driver.

There is already a kernel report about this.
