I, too, am using a Logitech Webcam communicate STX. And I, too, can't get it to work in Win 7 (64-bit, build 7100). I've done all the updates I can and still no love. I've tried installing Logitech's drivers
in WinXP and Vista modes and still nada. I have an older scanner that is facing extinction on Windows 7, too. Good thing I love WinXP - cuz it looks like I'm going back. So far, no compelling reason to "upgrade" to Windows 7. Too bad I'll be forced to someday.
