Bluetooth: btusb: missing device ID 13d3:3626 (Realtek RTL8851BE, IMC Networks rebrand)

Hi,

My Bluetooth radio (part of a Realtek RTL8851BE wifi+BT combo module,
OEM-branded "IMC Networks") is not recognized by btusb's device table,
so the Realtek firmware never loads and the radio does not work at the
RF level at all (confirmed: neither scanning from the device nor being
scanned by other devices detects anything).

Device details (lsusb -v):

  idVendor           0x13d3 IMC Networks
  idProduct          0x3626 Bluetooth Radio
  bcdDevice            0.00
  iManufacturer           1 Realtek
  iProduct                2 Bluetooth Radio
  bDeviceClass          224 Wireless
  bDeviceSubClass         1 Radio Frequency
  bDeviceProtocol         1 Bluetooth

Kernel log on enumeration:

  usb 7-1: New USB device found, idVendor=13d3, idProduct=3626, bcdDevice= 0.00
  usb 7-1: Product: Bluetooth Radio
  usb 7-1: Manufacturer: Realtek

This looks like the same situation as 13d3:3600/13d3:3601 (RTL8851BE,
added in commit adding "Bluetooth: btusb: Add RTL8851BE device
0x13d3:0x3601"), just a different OEM USB ID for the same chip.

Would it be possible to add:

  { USB_DEVICE(0x13d3, 0x3626), .driver_info = BTUSB_REALTEK },

to the device table in drivers/bluetooth/btusb.c, next to the existing
0x13d3:0x3600/0x3601 entries?

Happy to test a patch if needed


Thanks,


Daniel
