Hello everyone, I'd be really grateful if anybody can help me out with a problem I have... My computer just doesn't recognise my Galaxy s4 when I connect it via USB. Now the computer recognises every other phone I've connected to it, I've tested about 7 different phones. There is nothing wrong with the phone or USB cable, I had this verified by Samsung, and furthermore, the phone connects to every other computer I've connected it to. I've tested it on about 5 different machines. So I know there's nothing wrong with the phone, and there can't be anything with the computer or it's USB ports since other phones connect to it. This has been doing my head in for the past 3 weeks, so I'd be eternally grateful if anybody can shed any light on it. I've downloaded Kies and all the Samsung USB drivers, I even reinstalled a clean copy of Windows and even factory reset the phone, but all to no avail. I have an AS-Rock Motherboard, could that be the problem? but if that was the case, why do all other phones connect. Thank you.
