Bulk IN endpoint stops polling for packets

akhil a

Hi All,

I am facing an issue with USB driver on ARM platform. the bulk in rx endpoint stops polling for rx packets after some time, when the issue occurs I see(with USB analyzer) all the other endpoints(tx and interrupt) are operational and I don't see any abnormal packets on rx endpoint.

But when I do abort, reset and resubmit the rx buffers on Bulk IN endpoint , it starts polling for rx packets and able to receive packets. This issue is frequent event after after doing(abort, reset & resubmit), it stops polling for rx packets after some time(after 1-2mins).

Pls suggest me the possible cause for this issue.

Regards
Akhil
