Dear Sir,
We are experiencing many cases of USB connectivity issues on AM3359 target board from the field site. Typically the USB devices (multiple brands of the memory sticks) are plugging in and plugging out around several ten times onto AM3359 target board, there is a high probably to get the USB port to go DEAD and all downstream devices are no longer show on the computer Explorer screen. While this USB port was DEAD, we tested the other USB Port connector on AM3359 target board and that USB Port still worked. Once cold start the computer again, the USB port & device all work fine.
Per the AM3359 target board, we have referred application notes to get strong noise immunity on USB (specific to VBUS) line. Are there any reference design/advise on how to enhance the USB plugging/unplugging capabilities on AM3359 target board?
Many Thanks and regards,
Bentham Yang
