Hi,
I'm currently testing v2017.11 on my x86 platform using
the xHCI interface to load images via USB keys. But if
I don't have any USB key installed, U-Boot crashes:
=> usb reset
resetting USB...
USB0: Register 7000820 NbrPorts 7
Starting the controller
USB XHCI 1.00
scanning bus 0 for devices... 4 USB Device(s) found

### ERROR ### Please RESET the board ###
Using v2017.09 this problem does not occur:
=> usb start
starting USB...
USB0: Register 7000820 NbrPorts 7
Starting the controller
USB XHCI 1.00
scanning bus 0 for devices... 4 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
=> load usb 0:1 03000000 abc
** Bad device usb 0 **
Does anyone have a quick idea, which commit might have
introduced this regression?
Thanks,
Stefan
