A new Realtek device, the RTW8852BE, includes a BT part, which is not
currently contained in the tables in btusb. File btrtl already contains
some information for these devices. Thus far, two such devices are known.

These two known devices have the following lsusb outputs:

Bus 003 Device 004: ID 0bda:4853 Realtek Semiconductor Corp. Bluetooth Radio
Bus 002 Device 003: ID 0bda:887b Realtek Semiconductor Corp. Bluetooth Radio

The pertinent contents of /sys/kernel/debug/usb/devices for the second is
as follows:
