(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? BR, Jerome
