I'm using a QCNFA765(WCN6855) wlan+bt combo card on my arm SBCs. However some
devices completely unable to detect its Bluetooth USB device. I've tested it on
radxa's Rock 3A and Rock 5B and beaglebone ai-64. USB only detected on Rock 3a
at any kernel version(both downstream and upstream kernel detects). Other two
devices cannot detect it at all. lsusb doesn't report anything about this card,
dmesg reports no warning/error about usb.
