Andiry, perhaps you can un-fix it to test? > So do you mean the xHC controller should be re-initialized when it has restore error? I can try it but I've got two questions: 1. EHCI and OHCI only do a host controller reset when they lost power during resume. Does xHCI need to be re-initialized? 2. Does xHC re-initialization helps to resolve the device address conflict issue? I assume it comes from the xHCI specific address assignment mechanism.
