-Subject: Bluetooth: btusb: check conditions before enabling USB ALT 3 for WBS
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Some USB BT adapters don't satisfy the MTU requirement mentioned in
-commit e848dbd364ac ("Bluetooth: btusb: Add support USB ALT 3 for WBS")
-and have ALT 3 setting that produces no/garbled audio. Some adapters
-with larger MTU were also reported to have problems with ALT 3.
-
-Add a flag and check it and MTU before selecting ALT 3, falling back to
-ALT 1. Enable the flag for Realtek, restoring the previous behavior for
-non-Realtek devices.
-
-Tested with USB adapters (mtu<72, no/garbled sound with ALT3, ALT1
-works) BCM20702A1 0b05:17cb, CSR8510A10 0a12:0001, and (mtu>=72, ALT3
-works) RTL8761BU 0bda:8771, Intel AX200 8087:0029 (after disabling
-ALT6). Also got reports for (mtu>=72, ALT 3 reported to produce bad
-audio) Intel 8087:0a2b.
