I have a gateway NV series laptop running windows 7. I also have a HTC desire firmware 2.1. I am having a hard time connecting my phone to my laptop using a USB cord. When I plug it in, I chose the option of Mount as Disk Drive (because I like putting and taking off photos and videos to and from my laptop) and most of the time I am coming up with a USB device not reconizged error. When I first got the phone I had no problem at all with plugging it in. Then I started having some issues with it and every now and then that error would pop up and I was not able to access anything on my phone through my computer. I know it's not the cord or my laptop because my sister has the same exact phone and was able to plug it in fine. I did a full reset on my phone and it worked for a few days after, but now I am having problems again. Also, when my phone does recognize it it shows nothing in "removable disk". Does anyone know of anything I can do to fix this problem?
