This Realtek device has both wifi and BT components. The latter reports a USB ID of 0bda:4852, which is not in the table.

When adding the new device, I noticed that the RTL8852AE was mentioned in two places. These are now combined.

The portion of /sys/kernel/debug/usb/devices pertaining to this device is

Signed-off-by: Larry Finger Larry.Finger@lwfinger.net Cc: Stable stable@vger.kernel.org --- v2 - fixed the merge conflict. I was working from the mainline HEAD that does not have the 0x04c5:0x165c device. I also merged the two separate locations with RTL8852AE entries. --- drivers/bluetooth/btusb.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
