Dear Maintainer,
The TP-Link UB600 (Bluetooth 6.0 Nano USB Adapter) is not usable on current
Debian kernels. The device enumerates and btusb binds it via the generic
Bluetooth class match, but no vendor (Realtek) firmware is loaded, so the
radio is non-functional: it cannot scan for, or be discovered by, other
devices.
Tested, identical behaviour on: 7.0.13-1, 7.0.12+deb14.1, 6.18.12, 6.18.5.
CONFIG_BT_HCIBTUSB_RTL=y on all of them.
The USB ID 37ad:0600 is not present in btusb's device table ("modinfo btusb"
lists no entry for it), so no vendor quirk / firmware loader (BTUSB_REALTEK)
is applied and btrtl is never invoked.
Request: add device support for the TP-Link UB600 (USB 37ad:0600) to
drivers/bluetooth/btusb.c with the appropriate Realtek quirk, and ship the
matching firmware in firmware-realtek / linux-firmware if not already
present.
