Subject: Ugreen Bluetooth 5.3 adapter

Hi all,

I've been working on trying to get this to work.

I've applied this patch:


But I was still getting the following error:

Bluetooth: hci0: Opcode 0x c5a failed: -56

I added


as an additional quirk for the device, but now I'm getting

Bluetooth: hci0: Opcode 0x202e failed: -56

Which tells me that HCI_OP_LE_SET_RPA_TIMEOUT isn't supported. I'm not
at all familiar with the linux bluetooth drivers, so I'm not sure how to
work around this.  I didn't see another quirk I could register.

Any advice?
