https://bugzilla.kernel.org/show_bug.cgi?id=60824 --- Comment #81 from Andrés Rodríguez (hello@andres.codes) --- Hi Swyter, unfortunately I'm still unable to list the device. Blueman found no adapters and neither does bluetoothctl list. dmesg info messages say it's still being recognized and given the bcdDevice I assume the quirk is being applied but seemingly is not enough: [ 67.847429] Bluetooth: hci0: CSR: New controller detected; bcdDevice=0x2520, HCI manufacturer=10, HCI rev=0x3120, LMP subver=0x22bb [ 67.847432] Bluetooth: hci0: CSR: Unbranded CSR clone detected; adding workaround This is a cheap chinese dongle that says "CSR 4.0" on the side, I took a (crappy) photo of the PCB: https://i.imgur.com/3I5aKMZ.jpg and here's a stock one from the vendor showing the box and the dongle: https://i.imgur.com/wyjJTU6.jpg The super small nigh-unreadable text in the main chip says "AP1P181" Let me know if you want me to try anything else. -- You are receiving this mail because: You are the assignee for the bug.
