Hi Yang,

the controller reports

  fw_version: date = 09.08, number = 0x15d2

The firmware is not the linux-firmware one: aml_w155s2_bt_uart.bin from 
linux-firmware downloads without errors on this board and then never 
starts (no HCI event after the download). The one that works is the 
firmware embedded in the vendor Android libbt-vendor_aml.so of this box 
(X98Q, S905W2), 0x60000 bytes. I load it as aml_w1_bt_uart.bin.

If there is a newer firmware without this behaviour, I would be glad to 
test it, and if it fixes it I would rather drop the quirk than add it. 
Is the linux-firmware image meant for this chip revision, or should it 
start as well?

Kind regards,
Christian K.-D.
