This may indicates that you have corrupted firmware. Please check md5sum of your fw file /lib/firmware/brcm/BCM20702A1-0a5c-21e8.hcd:

Even though I confirmed earlier that the cited patch worked yesterday, I found that its behavior is inconsistent and erratic, though working partially. Despite the presence of several Bluetooth devices, only one or two devices are getting recognized, and getting disconnected off and on.The Bluetooth ON icon is also not appearing on the task bar display. Even with the one or two devices working, the "patch failure" output is seen against the "dmesg | grep -i Bluetooth" command

Another source of unstable working is underpowered USB connection or bad USB-cabling. Please check on another port, if dongle connected via cable, try connect directly to port. If connected to USB3, try to use USB2 port.

Hi all

I just stumbled by chance upon this topic and want to give the following hint. Try to disable the USB auto suspend feature:

sudo nano /etc/default/grub

Add the following value to the "GRUB_CMDLINE_LINUX_DEFAULT" line.

usbcore.autosuspend=-1

The result should then look like "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1". After that update the GRUB config with:

sudo update-grub

This may help or not. I think those Broadcom BT 4.x controllers can have sometimes a quite special behavior. And those with Apple branding are sometimes even more weird (especially if they have an older firmware) . Mine is a BCM94360CSAX and not even listed with lsusb. Only the "BCM2046B1 USB 2.0 Hub" entry appears.

Whatever, - it should be also added that there can exist a an additional problem with the bluez BT stack. This can be resolved by upgrading to a more recent version.

I also have a BCM20702A0 I'd like to try update because of poor sound quality issues and after trying lots of other avenues.

These .hcd files here are for BCM20702A1?
Is there a suitable file here?

I'm on Ubuntu 24.04 LTS
Kernel: Linux 6.8.0-31-generic

Check README.md on how to detect your device and required firmware for it.

I don't get the expected output at the first stage.

There's no information on the firmware version.

I've also tried installing the .deb package to no avail.

Please open separate issue and additional info about you hardware.

If you are on a Mac / Apple hardware then the easiest way is to boot up Mac OS. For example, versions like 10.11 "El Capitan" or newer are automatically updating the BCM94360CSAX BT controller to the latest firmware. But when it comes to Linux I have unfortunately no idea if those special "Apple" Broadcom controllers are at all supported in fwupd.

Well, my BCM94360CSAX BT controller seems to be supported when I run fwupdmgr get-devices but I it's unclear from where I can get the corresponding firmware files. Probably there exist a way to grab / download them via sysfs and make an own "firmware library". 🤔
