"Unknown Device" under device manager

[Kris]

OK, so I uninstalled my computer's two "USB root hubs" under device manager
in order to attempt solve an issue with a webcam. Now, they appear as
"Unknown Devices". Is there a way I could fix this so they are listed
appropiately? I also attempted to delete the two uknown devices and have the
computer search for new hardware, but they appear listed the same when found.
Any ideas?

How do I re-install the buggers when they keep appearing as"uknown devices"
when I attempt to do so?

Use the update driver tab for each unknown devices and look in the list and
pick the one for your usb
That would be the right choice to me for the fix.
Because when you uninstalled them Vista does not remove the drivers from the
driver dat file unless you tell it to and you did not remove them.
So go look.
