I've CCed new Andrzej's email.

Could you tell a bit more how to reproduce this issue? Which USB
function are you running on the target system? I've noticed that you are
using functionfs. Is is possible to get access to the usb function
daemon to reproduce the problem here? Which version of HiKey board are
you using?


Can you please apply this patch:

and see if this helps?
