Device manager can't see the devices

Please could some kind person direct me to an answer to this problem.

Dell dimension desktop. uses XP home. Family machine. 6 USB ports.

I got a message this morning which said "USB hub port overload"

The following were plugged in as they always have been - printer, scanner, web cam - one per port. I do not use a hub, since I have 3 ports free.

But none of them show any signs of life - eg the scanner normally whirrs and buzzes for a couple of seconds after being plugged in which it now does not do and the web cam little "I'm on" light does not glow.

I have been to the control panel->system->device manager. Here I normally find a long list of devices which reassures me amongst other things that each device is working properly.

The device manager window is completely blank. Just a white space, no list - nothing, not even the name of the computer. I tried to restart in safe mode. After selecting the SAFE MODE option in what looks like an MS-DOS screen nothing happens at all - so I don't appear to be able to start in safe mode!

So there are two questions.

1) How can I get the device manager list back?

2) What does a USB message about "hub port overloads" really mean?

skidzy, thanks, Kingfisher above got it in one. A very large number of the settings in Services(services.mcs) had been set to disabled.
Too many relatives of varying shapes and sizes here over the last few days I think.
So I have reset them back to automatic and that seems to have restored the system back to normal.
thanks again John
