I'm using the Seidio desktop cradle, and for the most part am very happy with it. Here's my question: For the life of me, I can't mount my Droid as a USB device when it's on the cradle. When I use the pull-down menu and select "USB Connected", nothing happens. As soon as I take the cable off the back of the dock and plug it directly into the phone, I'm able to mount it as a USB device. Is this normal behavior, or do I have a faulty dock?
