That particular error generally means that something is interfering with 
the USB data transmission.  It could be a poor cable connection, or it 
could be the mouse sending a bad signal, or it could be some sort of 
outside electromagnetic interference.

By the way, it looks like you don't need the entire patch.  Just the parts

should be enough to help.
