But when I originally submitted the patch = it made my dongle work just fine. So in theory using an older patched kernel should work.=20 Improvements are welcome, while getting a new dongle is a decent solution ideally we'd fix the counterfeit ones enough to work as well as on Windows.= The problem is that bluez is a moving target, with new modes being introduced a= ll the time, regressing these fickle chips. --=20 You may reply to this email to add a comment.
