From: mokshraj <mokshraj20@gmail.com> Date: Mon, 19 May 2025 20:07:26 +0530 Dear Linux Bluetooth Maintainers, I am experiencing an issue with my Bluetooth USB adapter after installing Linux on my Acer Aspire Lite AL15-41 laptop. While Bluetooth can be turned on and is visible in settings, my system is unable to detect other Bluetooth devices, and other devices cannot detect or connect to my system. My Bluetooth adapter has the USB ID 0x13d3:0x3601, which appears to be a Realtek chipset. Here is some information about my system: Problem: Bluetooth is enabled but cannot detect other devices or be detected by them. When it started: Immediately after installing Linux. Bluetooth Adapter USB ID: USB_DEVICE(0x13d3, 0x3601) Computer: Acer Aspire Lite AL15-41 Linux Distribution and Version: OS: CachyOS x86_64 Kernel Version: 6.10.2-rt14-arch1-6-rt BlueZ Version: 5.82 Through some investigation, I found a potential fix which involves adding a quirk for my specific USB device ID to the btusb.c driver. The suggested patch is as follows: Diff This patch adds my device ID (0x13d3:0x3601) to the list of Realtek devices that require the BTUSB_WIDEBAND_SPEECH flag. Applying this patch manually has resolved the issue on my system, allowing Bluetooth to detect and connect to other devices. I understand that the individual who provided this patch does not have the time to create a DKMS module for Arch Linux users. Therefore, I am submitting this patch for inclusion in the btusb.c driver. I believe this would benefit other users with the same Bluetooth adapter by providing a default fix. For further information about my device, you can refer to this Linux Hardware Probe URL: https://linux-hardware.org/?probe=b58f50ee34 Thank you for your time and consideration. Sincerely, Baymax(moskhraj)
