Bluetooth Driver not installing for Broadcom BCM4352HMB on Windows 11

Your screenshot indicates that the correct driver is installed.

The first one in your screenshot that shows the driver version and 8 MB file size.

Also, if it wasn't the right driver, the unknown device would not have disappeared.

I tried to find a pin diagram for the BCM card but came up empty handed.

I doubt that disabling secure boot will do anything to fix the BT not working, and if you can't disable secure boot without also enabling Legacy mode, your PC will not boot up with the drive having the GPT partition table.

Do you think uninstalling the BIOS will fix the issue?

You can't do anything with the BIOS.

I found out from someone on SuperUser.com that the pinout for PCIE mini cards are all made according to the M.2 specifications. What was throwing me off was that the arrangements of the pins on my BCM4352 were a little different; some pins were not present in their positions while in other PCIE mini cards they are present, but that is by design. Here is the typical pinout of an PCIE mini card:

And here is an image of the Broadcom BCM4352HMB:

In the Broadcom device it seems that pins 20 and 18 have been combined into one pin, and when I covered them along with pin 51 nothing happened, the computer still could not detect Bluetooth in Device Manager. In previous attempts at this I had covered pin 24 and pin 51, which disabled the Wifi, and I also tried covering pins 51 and 22, but nothing happened either. Do you have any suggestions?
