I've recently bought a new printer, a HP Photosmart 4280 using a USB port on Windows XP, pentium 4. After I install it, there were some problems, so I uninstall it, but after that when I tried to install it again, the computer showed a message saying USB device not recognized. So I thought it was the printer's problem, but when I tried other portable devices using a USB port, none of them worked either. What should I do? Please Help!!

What you need to do is go to your Device Manager and see if there are marked errors there.

Right click My Computer and select Properties.

From there click on the Hardware tab and then click the Device Manager button. Scroll down the list and see if there are any items listed with a yellow exclamation mark next to them, especially something to do with USB root hub.

Write down all possible errors and report back with each one and we'll see what we can do.

Good luck.

Ok, I went and check my device manager, but it doesn't show any errors with the the USB, but when I just plug in a USB to my computer a message pops up and says that the device is malfunction and there's an error with an unknown device on the device manager, but few seconds later it shows that everything is fine. When I click USB on my device manager, it gives me two SiS 7001 PCI to USB Open Host Controller, a SiS 7002 USB 2.0 Enhanced Host Controller, two unknown device (I know for sure that the USB that I plug in is suppose to be one of these, but it shows that there's no device connected). and also a USB 2.0 Root Hub, two USB Root Hub.

That's very odd. Maybe reinstalling the drivers for your USB ports might do the trick, but I'm not sure.
This is one problem that i can't recall seeing before. I'll report this to the other moderators around here and see if they happen to have any answers.
