Hello, change seems to be unfriendly to RPi3B+, it allows to enter 'U-Boot>' shell but usb keyboard does not respond. Keyboard is detected by 'usb info' in v2023.01-rc3, not in v2022.10. When reverted, usb keyboard works as expected.
Anybody sitting front of RPi3B+ care to confirm?
For me an USB keyboard connected to a Raspberry Pi 3B+ is only detected when something is typed during the probe.
The message
usb_kbd usb_kbd: Timeout poll on interrupt endpoint
is a sign of nothing typed on the keyboard and then it does not work.
It is limitation of the dwc2 hardware with hardwired USB hub.
Same on both v2022.10 & v2023.01 rpiarm64 and rpi_3 configs.
Thanks
Michal
