I've been trying for days to get the usb drivers working, so I can eventually root my phone. However, I have had no luck. I apologize for my lack of grammar, but im just going to start listing things that might be relevant to my problem. I have Windows 7 64 bit I have a Galaxy S2 Skyrocket Plugging the cable into my phone and PC (USB) does nothing except charge. My phone has "USB debugging" enabled. My device shows up under "other devices" in device manager, but it says "not working, needs driver update (or something to that effect). Can't find drivers when it searches. Downloaded drivers manually, and get the error "Samsung mobile USB composite device" failed to install. Tried pointing driver update to the folder named "usb_drivers" that was created by downloading something from google via the SDK manager. I'm lost. Any help?
