Have you tried uninstalling LGS and reinstalling it. There are no drivers for the mouse. If the cursor moves when you move the mouse, then the driver is good. LGS is just there to give you the button programming capabilities. I have a G700 and LGS has given me a couple of problems with sometimes losing the devices. A reinstall has always fixed the problem.

OK, it's probably one of 2 problems then. Either the LGS software is not installing correctly, or the mouse is not reporting it's hardware Ids correctly. I know you said you reinstalled the software several times. Was it always from the same downloaded file or did you try downloading it a second time? If the file corrupted duringthe download, using the same one over again won't do any good.
