https://bugzilla.kernel.org/show_bug.cgi?id=60824 --- Comment #265 from guimarcalsilva@xxxxxxxxx --- Let me preface this by saying that this specific dongle might be already broken since even on Windows it works but disconnects after a while. Personally, I've given up on those fake adapters and ended up buying a good one, but I'll share my test results here just in case it helps someone else. For me, with this latest patch (On Arch with kernel 6.1.1-arch1-1) the dongle still doesn't work. When I boot up with it connected, btmon gives it an empty index: > New Index: 00:00:00:00:00:00 (Primary,USB,hci0) dmesg outputs: > [ 4.915236] Bluetooth: hci0: CSR: Setting up dongle with HCI ver=9 > rev=3120; LMP ver=9 subver=22bb; manufacturer=10 > [ 4.915243] Bluetooth: hci0: CSR: Unbranded CSR clone detected; adding > workarounds and force-suspending once... > [ 5.466031] usb 1-5: new full-speed USB device number 5 using xhci_hcd > [ 9.953845] Bluetooth: hci0: CSR: Couldn't suspend the device for our > Barrot 8041a02 receive-issue workaround > [ 9.953958] Bluetooth: hci0: HCI Delete Stored Link Key command is > advertised, but not supported. > [ 9.953967] Bluetooth: hci0: HCI Read Default Erroneous Data Reporting > command is advertised, but not supported. > [ 9.953974] Bluetooth: hci0: HCI Set Event Filter command not supported. > [ 12.086015] Bluetooth: hci0: Opcode 0x c03 failed: -110 Curiously, if I disconnect it and reconnect it quickly, btmon does give it a valid index: > = New Index: 00:1A:7D:DA:71:10 (Primary,USB,hci0) And Dmesg outputs the following (notice the two last messages are different): > [ 79.189612] Bluetooth: hci0: CSR: Setting up dongle with HCI ver=9 > rev=3120; LMP ver=9 subver=22bb; manufacturer=10 > [ 79.189644] Bluetooth: hci0: CSR: Unbranded CSR clone detected; adding > workarounds and force-suspending once... > [ 79.189654] Bluetooth: hci0: CSR: Couldn't suspend the device for our > Barrot 8041a02 receive-issue workaround > [ 79.190111] Bluetooth: hci0: HCI Delete Stored Link Key command is > advertised, but not supported. > [ 79.190124] Bluetooth: hci0: HCI Read Default Erroneous Data Reporting > command is advertised, but not supported. > [ 79.190131] Bluetooth: hci0: HCI Set Event Filter command not supported. > [ 79.231713] Bluetooth: hci0: unexpected cc 0x0c25 length: 2 < 3 > [ 79.231781] Bluetooth: hci0: Opcode 0x c25 failed: -38 This only happens if I connect it quickly after disconnecting, it I take a few more seconds, btmon still gives it an empty Index. Either way, the dongle doesn't work at all and doesn't even show up in Plasma, even with a non-zero Index. I hope this can be useful. -- You may reply to this email to add a comment.
