Dear Sarah,
dear Andiry,
as I do not know wheter or not attachements to emails are tolerated in the
mailing list, I send this directly to you - please advise if I'd send that
somewhere else.
Please find attached the result of dmesg after logout - login. According to
your request, I activated both CONFIG_USB_DEBUG and
CONFIG_USB_XHCI_HCD_DEBUGGING.
Let me know if you need anything more than this .... thanks again,
The dmesg is catched with test patch applied, right?

Here software wants to set interface again, but the ep is already
disabled by the last config ep command.
I wonder why I do not see the Signal while waiting for configure
endpoint command line in the earliest dmesg.
Thanks,
