+Jeremy,
I review the patch and think it is reasonable, but I want to know some more detail information
1. Can you provide the detail debug log about USB?
2. The symptom always can be seen or have fail rate?
Best Regards
Guomin

Hello,
could anyone review this PATCH?
We encountered the USB enumeration problem and the patch is based on the Microsoft post as below.
