Trouble installing USB devices (Windows 98 SE)

by pjuztarizo / February 15, 2004 8:59 PM PST

Followed the instructions that came with the webcam: installed drivers and software first. Then connected the webcam to the USB port: "Unknown Device" came up.
Went to Start, Control Panel, System, and found out that, there is also a problem with the video driver.
It shows: unknown PCI video device (or something like that), despite that the correct video driver is already installed.
Please help.

Bottom line, concerning an unknown listed somewhere is to ascertain whether DM lists a problematic device or a software issue more than once somewhere else in the tree but really that device is currently recorded appropriately in the tree where it should have been in the first place and is appropriately installed and working. Sometimes issued occur which was caused initially by some anomaly that caused an "unknown" entry but later through tweeking and ignoring that "unknown" a user managed to set things straight elsewhere but the "unknown" entry still exists. Note that when second issues have occured -- an "unknown" and a correctly recorded entry elsewhere, it is recommended that the latter be deleted and concentration made on correcting the former -- particularly if it is hardware related. Understand however, this may be "shooting from the hip" only to see what happens -- since your guess may be as good as mine.

Microsoft does not install motherboard or USB filter drivers for you. It's all a matter that floors new Windows (and old) users. has many articles about this, but the short version is that we get to hunt down the motherboard and possibly USB drivers for the motherboard or card.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
