Device Manager Problems

I have a problem when reinstalling Windows 95. When the installation process has finished and you go into the Device Manager, there are 2 ‘Other Devices’ with Yellow question marks.
THe PC’s are Compaq Deskpro 2000 P166 and the following devices are not recognised.
PCI Early non VGA Device
Universal Serial Bus

Could anyone point me in the right direction of how to resolve this situation. I’ve looking on Compaq’s Web site but there doesn’t seem to be the appropriate drivers there.

KindRegards
