            Bug ID: 219234
           Summary: btusb: regression in rtl8761bu firmware
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Bluetooth
          Assignee: linux-bluetooth@vger.kernel.org
          Reporter: alexander@tsoy.me
        Regression: No

First of all, sorry if this is incorrect place to report firmware issues.

Since commit [1] communication between rtl8761bu and Xbox Series X controllers
is very unstable. There are frequent reconnects that makes the rtl8761bu
controller unusable. Reverting mentioned commit fixes this issue.

Xbox Series X controller is tested with several latest BLE firmwares. There are
no any errors in the kernel log.

This issue was also reported to xpadneo driver [2]
