My device has the same product description, but appears to the system as a
different product code. And fails.
[ 444.694776] usb 4-2: New USB device found, idVendor=0a12, idProduct=0001,
bcdDevice=25.20
[ 444.694792] usb 4-2: New USB device strings: Mfr=0, Product=2,
SerialNumber=0
[ 444.694799] usb 4-2: Product: CSR8510 A10
[ 445.284957] usbcore: registered new interface driver btusb

[ 445.286711] Bluetooth: hci0: LMP ver=6 subver=22bb; manufacturer=10
[ 445.286714] Bluetooth: hci0: CSR: Unbranded CSR clone detected; adding
workarounds and force-suspending once...
[ 450.486604] Bluetooth: hci0: CSR: Couldn't suspend the device for our Barrot
8041a02 receive-issue workaround
[ 450.486705] Bluetooth: hci0: HCI Delete Stored Link Key command is
advertised, but not supported.
[ 450.486712] Bluetooth: hci0: HCI Read Default Erroneous Data Reporting
command is advertised, but not supported.
[ 450.486717] Bluetooth: hci0: HCI Set Event Filter command not supported.
[ 452.500066] Bluetooth: hci0: Opcode 0x0c03 failed: -110
It enters a broken state when the force-suspend command is issued, then
timeouts the reset command afterwards.
