That's not listing anything at all. It should list the root hub(s).

The one on my Thinkpad T42p appears as a USB device. That one is
inactive by default; I have to press Fn-F5 to activate it. When I do
that, a Bluetooth LED near the NumLock LED lights up, and the device is
visible on lsusb. (Yes, it works properly, but I don't have much use
for it as I only have 1 Bluetooth-capable device.)

Sounds like it's inactive if it's there. Check your laptop's manual for
info on Bluetooth. Since Bluetooth uses power, a lot of the time,
laptops have switches of some sort to turn it on/off. That means you
don't waste valuable battery minutes running Bluetooth when you don't
need it. HTH anyway,
