Hi, I found a problem just like in the older discussion "Question about error from xhci-hcd", there was a xhci error "no room on ep ring" when plugin rtl8192cu on USB3. (it works on USB2) After applying Larry's patch "rtlwifi: rtl8192cu: Change firmware upload to use block writes", I still get the same error "no room on ep ring". But under the same compat-wireless version, rt8712 works on USB3. Does anyone still encounter this problem after applying this patch? or do I miss something/patches?
