#69076 — Bug#979505: linux-image-5.10.0-1-amd64: please apply patch to fix USB adapter initialization failure (rtl8761b chip)

Package: linux-image-5.10.0-1-amd64
X-Debbugs-Cc: kenhys@xdump.org
Version: 5.10.4-1
Severity: wishlist


The problem:

USB bluetooth adapter is not correctly initialized
when rtl8761b chipset is used.
(Thus, failed to initialize as a bluetooth controller correctly)

This issue was fixed in linux 5.11, so please backport the following patch
to 5.10. [1]

  Bluetooth: Fix attempting to set RPA timeout when unsupported

  During controller initialization, an LE Set RPA Timeout command is sent
  to the controller if supported. However, the value checked to determine
  if the command is supported is incorrect. Page 1921 of the Bluetooth
  Core Spec v5.2 shows that bit 2 of octet 35 of the Supported_Commands
  field corresponds to the LE Set RPA Timeout command, but currently
  bit 6 of octet 35 is checked. This patch checks the correct value
  instead.


How to reproduce

1. boot with linux-image-5.10.0-1-amd64
2. connect usb Bluetooth adapter (rtl8761b chipset)

Expected:

The initialization process succeeds without error.
