I have tried to down load the Windows 7 drivers for my HVX200. When the message came up saying "connect P2 device" I plugged in my camera with a 2.0 USB data cable. The PC did not recognize a new device. I tried connecting to 3 different computers using 2 different cables and all USB ports. Nothing happened. I made sure my camera was on "USB Device" and tried again. Same results. Now I have a camera that won't talk to my computer so I can't transfer my video on the P2 card for editing. Any suggestions?
