I upgraded this morning to the latest stuff in devel but didn't see 
what you're seeing with my USB Camera Interface, Keyboard, Mouse or 
USB WinTv Capture Thingy. The Camera detection created the mount 
point '/dev/uba1' which I had to manually mount. The last batch of 
rpm updates installed here were:

Could your problem be associated with the SMP aspect of the kernel 
or the particular USB device type?  I'd be happy to test anything I 
can here to help you isolate the problem ...
