I can't get Bluetooth (keyboard & mouse) to work after upgrading F14 -> F15 (amd64). BT worked OK in F14.

lsusb gives:

I take it some keyboard works

did you check to see just how many fedora 14 rpms are still installed ? and orphaned or might be "just messing things up"

also does the keyboard work if you make a new user ?
