The enable button continues to show, even after clicking it multiple times. The Bluetooth widget in the system tray allows me to 'add devices', but the dialogue shows no devices, even though I have bluetooth devices active and ready to pair. ## $ lsb_release -rd No LSB modules are available.

When I internet search for chip ID 13d3:3602, I find a couple pages that refer to it as the Mediatek MT7925 card. E.g.: https://github.com/bluez/bluez/issues/995 Conclusion: The manufacturer is MediaTek; the vendor is IMC Networks; the product name is Wireless_Device and the card goes by the name Mediatek MT7925. I've looked online for linux drivers for MT7925 and thought about putting those drivers on my system in the directory /lib/firmware/mediatek/mt7925 . However, the drivers already are in that directory. So the system already has the firmware for this device. The problem is that either linux itself or some related software such as bluez is not initializing the device. This strikes me as an unintended bug. I have seen discussion online that the MT7925 card works starting with kernel 6.11.5, on another Debian OS (nix). Kubuntu 24.04, however, is on kernel 6.8.0. I like the stability of 24.04 and have put a lot of time into setting up hibernation and software. I hope a fix can be made available for my bluetooth. What I expected to happen: Bluetooth can be enabled, can see devices, can pair with devices, and can deliver audio. What happened instead: Bluetooth cannot be enabled, so it cannot see devices, pair with them, or deliver audio.
