Hello,
I've recognized a problem with u-boot and USB devices at RPi Zero.
If I power up the device, it looks like this:
starting USB...
USB0: Core Release: 2.80a
scanning bus 0 for devices... 3 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
scanning usb for ethernet devices... 0 Ethernet Device(s) found
Booting from: mmc 0 ubldr.bin
Everything is working correct and a USB LAN adapter is detected.
If I reboot the device not all USB devices are recognized and I get an
error from u-boot ("unable to get device descriptor"):
scanning bus 0 for devices... unable to get device descriptor (error=-22)
2 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
scanning usb for ethernet devices... 0 Ethernet Device(s) found
Booting from: mmc 0 ubldr.bin
reading ubldr.bin
224136 bytes read in 31 ms (6.9 MiB/s)
Only the USB Hub is detected, the USB LAN adapter stops working.
Is this related to u-boot? Could it be due to "faulty" USB device?
I guess, I need some help, to get this working.
