<h4>Deactivating the internal Bluetooth controller</h4>
<p>The Thinkpad X220 has an internal Bluetooth controller, but 
<a href="/articles/2025/AC7260-wifi-card-on-Thinkpad-X220.html">I installed the AC7260 wifi/bluetooth card</a>.</p>
<p>Unfortunately the default card remains the internal one, so autoconnect of my headset doesn't work.</p>
<p>In order to block the internal device, I made a UDEV rule in /etc/udev/rules.d/91-bluetooth-hci.rules</p>
<p>After obtaining the id with lsusb:</p>
<pre>SUBSYSTEM=="usb", ATTRS{idVendor}=="8087", ATTRS{idProduct}=="07dc", ATTR{authorized}="0"</pre>
<p>Reboot, and the AC7260 Bluetooth card is now the default.</p>
