Something in that timespan caused a regression. It was still an improvement, because the counterfeit detection worked fine and the dongle talked back and forth, but it suffered from weird connection problems, so it probably didn't play well with some of the Bluetooth stack changes introduced recently. As you said, my patch on kernel 5.7 worked more or less fine. I haven't had time to properly track down the issue or see what happens in newer kernel versions with the patch included (from 5.8.2 onwards, I think). https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/diff/drivers/bluetooth/btusb.c?id=v5.8.2&id2=v5.8.1 But maybe it has ironed out itself. ¯\_(ツ)_/¯ If anyone has time to do some regression testing to narrow down the issue and better document what's going on, it would probably help a lot. -- You are receiving this mail because: You are the assignee for the bug.
