We are seeing timing issues with transcend usb sticks. These devices seems to require more time than regular devices for the control messages to reach device. Add 1ms delay before sending control message to fix trancend device detection issue.

In case you set 'usb_pgood_delay=2000' in U-Boot environment and re-test the USB stick, does the issue go away too ? This would increase the time from power Vbus enable to USB enumeration, it usually tends to fix such odd hardware too.
