This is what happened to a friends computer. Her daughter had the
camera connected and disconnected using "Safely remove hardware
device". Ever since then the only USB device the computer will
recognize is the camera. The previously working printer and flash
drive show as "Unknown Device". She has tried to rectify this using
system restore but no luck.

Any suggestions wil be greatly appreciated.

Make sure she is not using a USB hub. Look in the device manager.

You might try deleting/removing the cache file from folder:
c:\windows\inf\INFCACHE.1
(Note that the "inf" folder is hidden)

Not using USB hub. Have tried all ports. Device manager says
controllers and hubs working. When we plug camera in device manager
says "USB Mass Storage Device" but anything else comes up as "Unknown
Device"

Then I would think the Device Manager should show these Unknown Devices.
And I believe they are listed under as Unknown Devices as well. Select
properties and you should see how to reinstall the missing driver.
