Can a video camera Panasonic NV-GS57 (it has a USB 2.0) transfer video that was recorded to a windows 7? It is equipped with usb driver but fits Windows XP, Windows 2000. (one of the files that installed I made it "Run this program in compatibility mode for Windows7" but it doesn't sense the camera connection). I would be grateful for any help you are able to provide
A driver for Windows XP/2000 will almost certainly not work with Windows 7. Actually forcing installation of old drivers using compatibility mode might introduce system instability (assuming the installation program managed to get the driver installed and not just the accompanied programs).
Check your manufacturers website for update drivers for Windows 7.
