Without this entry btusb treats the device as a generic Bluetooth adapter and never loads the Realtek firmware, leaving the controller on its ROM firmware. In that state it advertises and scans actively, but never reports advertisements during passive scanning. LE connections initiated by the kernel wait for a passive-scan report before issuing LE Create Connection, so connecting and pairing from BlueZ time out without any error from the controller. The same product is also sold with the ID 0x2c0a:0x8761, which is already supported. lsusb -v output for the device: Bus 001 Device 010: ID 14b0:047a StarTech.com Ltd.
