So, I just bought a zune and when I go to hook it up in my USB connection sometimes it will not show up at all and other times it will show up, start uploading my songs and what not but then stops in the middle and says there is no zune plugged in and it shuts off. I haven't been able to have it in there long enough to even charge it up so I can use the default music on there. I have had problems with other things that I try to hook up to USB but most of them work most of the time. I tried my zune on another computer and it worked fine. So, are my USB connections messed up? I really want to avoid having to buy a new motherboard because I'll have to redo my whole computer just to get my zune working? IS there any other option or way to fix my USB connections?
