I uninstalled the LG United Mobile Driver through CCleaner and then reinstalled it but otherwise I don't see any LG drivers under my Device Manager. I tried alternate usb ports, too.
Edit: Works now. Apparently I need to have the debugging mode turned on.
I wonder if I installed the OS right. My Internal SD only has 7 folders while my external has 14. I recall having twice as much stuff in internal originally and that I could put things such as music in there. I no longer have a Music folder in internal but I see it in External.
