Hi,
USB is not working on my Olimex A64-Olinuxino-1Ge4GW Rev. D, no matter if I use the u-boot variant with or without eMMC (but that's no surprise). I use the version provided by Debian, 2020.04+dfsg-1 withe image provided by Armbian it didn't work either.
I attached boot logs with and without attached USB key.
In both cases one gets an "EHCI failed to shut down host controller." while loading the kernels fdt.
The error message with attached USB key is:
scanning bus usb@1c1b400 for devices... ERROR: USB-error: DEVICENOTRESPONDING: Device did not respond to token (IN) or did not provide a handshake (OUT) (5) ERROR: USB-error: DEVICENOTRESPONDING: Device did not respond to token (IN) or did not provide a handshake (OUT) (5)
USB device not accepting new address (error=20)
After booting Linux there is still no USB available, but that's a different bug I guess ;-). I attached the dmesg log anyway.
I also filed a Debian bug report about the issue: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=956923.
Best, Philip
