Does the console log show any USB errors? Otherwise there would be no reason for it to be slow and erratic, unless it was a wireless Mighty Mouse, but then we would be talking about Bluetooth, unless you were using a USB Bluetooth adapter...Interestingly, if I remove the GenericUSBXHCI.kext and let OS X use it's own driver the bus shows up in USB. I tried plugging an Apple Mighty Mouse into the card and it shows up. However, the movement is EXTREMELY slow and erratic.
