Already tried that.. and this is not a USB Hub, this is the Bluetooth device for the mobo

Tried older and new bios?

I have the original bios that came with the board on 2nd Bios, First Bios I have the latest one 1.04

So you're saying it happens on both?

Yes.. did not notice at first. thought it was working after i reinstalled my OS. But it happened again.
It does work eventually. Bluetooth being recognized again. The USB Descriptor fails (Disappear) But this is by completely draining the system of power. Unplugging the PSU from the wall. Then it works for an hour or 2hrs. Then completely disconnects again

I see. Sounds like a hardware issue for sure.

Can also be resolved temporarily by Disable M.2 E on bios.. booting it up on windows and re-enabling it back again on bios. it will work.. but same symptoms, will just work temporarily. Wifi works. Its only the bluetooth that disappears
 

attached example of it being detected then failing
