Bug description:
[Impact]
Touchpad on a ByteSpeed C15B laptop is not working.
User will need to add i8042.noloop=1 to boot options to make it work.
[Fix]
* a48491c65b513e ("Input: i8042 - add ByteSpeed touchpad to noloop table")
This fix can be cherry-picked into all affected releases.
[Test Case]
Test kernel for Bionic / Focal can be found here:
https://people.canonical.com/~phlin/kernel/lp-1906128-C15B/
And they have been tested with positive test results.
[Where problems could occur]
The fix is just a small and simple hardware quirk. I can't think of any
potential problem for now.
== Original Bug Report ==
Touchpad hardware is OK and works for Win10. Not working for live disc, not
for 18.04 and not for 20.04 after upgrading. I've attached a Logitech wireless
mouse with its USB adapter and that works. Bluetooth is also missing, but I
have not started trying to skull that out. I'm happy to help try debugging
things, and to help resolve the issue.
