Hello,

There are USB problems with P5020 boards with the latest Git kernels.

Some users reported the following error messages:

I don=E2=80=99t have a P5020 board here. That means I can=E2=80=99t bisect a=
nd test. Therefore I need your help. The problematic Git commit must be some=
where between 22/08/18 1:20 PM UTC and 23/08/18 10:49 AM UTC.
The Git kernel from 22/08/18 1:20 PM UTC works with USB devices.
Could you please compile a Git kernel and test it on your P5020 board?

Thanks,
Christian=
