Hello. I just bought the Panasonic HVX200 camera. I've owned a Sony DSR-PDX10 for years and always connected through the firewire cable. Its always been that one and not a usb like the ones I use for my external hard drives. Since my firewire cable for my last camera didn't fit in the slot for the Panasonic, I found some cables that did fit into the USB 2.0 port on the camera, and then connected it to my PC desktop via the USB ports that I always use for my hard drive. It didn't do anything. The computer won't recognize the camera or my camera won't connect to the computer. I can't figure out what to do. I unplugged the usb and plugged in the hard drive, and it popped right up, so I don't think its the port. Is there something I'm missing. I couldn't find any answers in the manual. Thank you.
