(Get the code!)
Still happens on 3.5.0-41-generic.
I have recently observed a variant (and the symptoms are active now on the laptop I'm writing with).
When bug happens, plugging a device on one of the two USB3 ports powers the device but Linux does not detect anything (nothing in dmesg).
Plugging the same device on one of the two USB2 ports (which never suffered the problem) works normally as it always did.
Heres the output of lsusb when all 4 USB ports are free (nothing plugged) :
