Hello there!

I recently purchased the tplink ub500 after I checked that it is supported for my kernel (6.4.0). However, whenever I try to use it using bluetoothctl of blueman-manager, the result is the same: "No controller available" and "No adapter(s) found"

I downloaded the firmware as specified but that did not help. I then went through the entire patch, step-by-step and did not encounter any errors. But the end result was the same. The adapter is not detected for use by Bluetooth but is detected when I run lsusb.

Any idea what I can do or what might be happening?

Hello,

Thanks a lot for the guide. It's very helpful !

I met an issue with the sudo modprobe -v btusb command, though.

insmod /lib/modules/5.15.0-52-generic/kernel/drivers/bluetooth/btusb.ko 
modprobe: ERROR: could not insert 'btusb': Invalid argument

Any idea ? Thanks

There seems to be another version for both this and the 4.0 dongle. Only found one mention of them where it was said that they're the same but was never sure.

Have you been able to tell if there was a change in chipset or firmware or whatever?
