Hi Bryan,
Sorry for the delayed reply. The sequence 'usb start' -> 'usb stop' -> 'usb start' works fine on Davinci and OMAP platforms.
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?
Best Regards, -Bryan
Thanks, Thomas.

Hi Thomas,
I'm still debugging the MUSB driver on my Blackfin board. I got a issue here: https://blackfin.uclinux.org/gf/project/u-boot/tracker/?action =TrackerItemEdit&tracker_id=153&tracker_item_id=4794
- when the board power on and run 'usb start', the usb
function is ok for usb storage usage. 2. then I tried 'usb stop'. and run 'usb start' again. usb device cannot be found.
Is that OK on davinci or omap platform?
Thanks -Bryan
