Subscriber Lee Pentz wrote about his Logitech Webcam:
USB 2 port does not recognize Logitech Webcam. Software installation from disk went smoothly, but when it comes to Audio and Video Setup the program says there is no webcam attached. Device Manager does not show it either. To the adjacent USB port the printer is attached, it works OK (a few days ago the printer was not recognized either, but after disconnecting the power to the entire setup: surge protector, modem, router, etc. then reconnecting, the printer works). I have WinXP Prof, SP2
When you have a situation like this, your first stop should be the manufacturer’s web site to look for updated software and an updated driver. That’s a good step for almost any hardware.
In this case, I’d go to Logitech’s web site to look for a new version of the Webcam driver. If you find one, download it.
You’ll probably have to go through a driver install as if the unit was brand new — note that some hardware requires that you install the software FIRST, while other says to plug in the hardware and then install the software. That distinction is very important.
Go to Start, Control Panel, Performance and Maintenance, System, Hardware, Device Manager. (If you’re using the "Classic" view of the Control Panel, you won’t have the "Performance and Maintenance" step.)
Look for your web cam in the device manager. It’s probably listed in some video or usb section of the device manager. My best bet would be in a category called “Imaging Devices,” which is where a scanner shows up. Windows should know it is there and disclose whether Windows is able to talk to it or not.
By the way, just because Windows can doesn’t mean Logitech’s device driver or software can. [Been there, done that, with my wife’s scanner.]
If you find the Webcam listed, select it and then REMOVE it. Then reboot. That will let you install the Webcam as if you were starting over.
Lee sent a followup message this morning:
IT’S WORKING! I followed your instructions, uninstalled the program, reinstalled it, connected the device at the exact time, and voila! I don’t know what was different the first time (I know that one USB port must be defective). Terry, thank you very much for your advice, I really appreciate your help.
