Hi,
i want to report an very old issue (AFAIK this never worked) on
Rasberry Pi boards without onboard USB hub (e.g. Rpi 3 A+ or Zero). In
case a USB device like mouse or keyboard was connected during boot of
the board, USB wasn't functional (device powered, but no reaction to
input). A reconnect of the USB device doesn't have any effect.
I enabled DWC2_DEBUG in the kernel config and get the following in for
the bad case (device connected during boot):
