Has anyone ever managed to get the USB lines on the T60 WLAN slot to
work? I plugged in an Intel 7260 802.11ac + Bluetooth card, and it is
reportedly using USB for bluetooth and PCIe for WLAN. My problem is that
the Bluetooth part of the card doesn't even show up in lsusb.

This thread made me wonder whether this is just an issue with broken rfkill.
