First off, I have a Dell Dimension 2200 with four USB ports in the rear and one in the front. For months, I was able to use the following external devices: An Acom 60GB hard drive; an Iomega 16x10x40 CD/RW, an I/OMagic 16x DVD rewritable, a Sandisk 1.0GB flash drive, and a High Speed USB 2.0 7-port hub. All of sudden none of them operate, with a message popping up saying "Device Not Recognized" or flat out saying there's a malfunction with the device. I have unsuccessfully tried the troubleshooter, gotten no help from Microsoft, attempted to find drivers for all of these, and nothing works. I have deleted the root hubs and the so-called unknown USB devices from my device manager, then restarted in the hope that my computer would be able to recognize all of them. No luck. I have checked multiple forums for advice, and it's gotten me nowhere. Has someone been in a similar situation and tried something that worked, or is anybody a USB expert who might be able to give some suggestions?

Unplug everything, turn the machine off, then turn it on with nothing connected. Then attach the items one at a time and see if they are recognized.
Are all of your items hooled up through your hub? If so is it a powered hub or a passive hub (passive $5, power $25 + it plugs into wall) if you are running all of that on a passive hub there may not be enough power to run everything so they stop. Try direct connecting them to your machine or getting a powered hub.

But does the preinter remain working? Try downloading the latest drivers for your printer. Are you sure it is the printer and not some other USB device it is wittering about? I have to admit I tend not to take much notice of these warnings anymore if my hardware continues to work - some devices seem to have some type of alter-ego leading the PC to try to recofnise it as something other than what it is. If you still have problems then the best course of action is to go to the HP web site and have a look at their FAQs or email their customer support centre. They are usually fairly helpful although you may have to wait a while to get their assistance!

Well, you've started to troubleshoot and done the the things I would have done. There is possibility there is something wrong with your USB card or possible connections. Try pulling the card out and 'resetting' it (sticking it back in). It could have worked itself loose a little. This is especially true if NONE of the usb ports are working......
There's always the potential that your card wen't kaput..... they're cheap and it's just a matter of sticking in the card (and there's most likely a driver that comes with it). Not sure if XP automatically recognizes USB cards.... it should come with a CD.
