Multiple bluetooth interface problem

I have a desktop with a bluetooth usb module, built-in ethernet and a pci wireless card with bluetooth and wifi.
I've bought the usb module since the bluetooth of the pci was crap.
I'd like to keep the wifi interface cause it could be useful and disable the other one.
Do you think it's possible?
At the moment I only managed to disable the pci card at all.
By default arch keep using the pci bluetooth.
Thank you.

Yes, you can do it: https://www.projectgus.com/2014/09/blac … rom-linux/

(The internal bluetooth is also a USB device.)

Re: Multiple bluetooth interface problem

The thing I don't want arch to use is the Bluetooth from the PCI and keep the wifi from the same card and the Bluetooth from the USB.
At the Moment I blacklisted the card itself totally.

wifi and BT will typically logically show up as different devices w/ the wifi on the PCI and the BT on the USB.
Also some kernel modules have features to flat out ignore the BT, but that's even more specific and w/o *any* details on your setup there's no way anyone here can give you certain advice.

Your question right now is "I have thing but don't want to use thing but keep other thing. Is this possible?" - we need to scratch the "thing"s out of that line.

Re: Multiple bluetooth interface problem

Sorry but English it's not my first language, I'll explain myself better.
I have a Qualcomm Atheros AR9462 Wireless Network Adapter which include Bluetooth, Wi-Fi support and is a PCI card. Its Bluetooth is trash and even if I installed all the possible drivers it doesn't work properly. I tried in Windows first and then here but the result it's the same.
So I bought a TP-LINK Bluetooth adapter, which works great, but it doesn't have Wi-Fi.
I don't really need the Wi-Fi support since I use Ethernet, but I'd like to know if it would be possible to keep only the Wi-Fi from the Atheros, so arch choose the TP-LINK by default to provide Bluetooth.
Thank you.
