I have tried all the drivers and did all the research I could do. I downloaded Google universal driver, Koush drivers, and LG drivers but I still get a "USB device not recognized" error. I have turned on/turned off USB debug and checked MTP in the setting. I have tried all of the non-OEM cable I have and none works.
Have anyone had this problem and solved it?
PS. my phone is stock 4.4.2
