Thanks for the reply. And 2 more questions: - there is no timeout control in the wait_until_xxx_ready() functions, so when there no device plugged in u-boot will hang in these endless loops. - there is no root hub control, so we cannot use 'usb info' to get device 0 root hub config info do you have any plan to add these?
