View Full Version : USB devices not recognized

09-27-2007, 02:22 PM
I have a Dell Precision 360 where all 6 of my USB ports will not recognize any more devices. Under device manager it says they are working properly. I have updated my chipset, uninstalled and reinstalled my USB controllers and still nothing. Any ideas???

first thing i would try is a pci usb card. If the devices are recognized with the addin card....i'd suspect a motherboard issue. Where the usb ports working prior to this post?

They were working about a month ago. I don't use my desktop much, but I previously had Windows 2000 pro installed on it and all of a sudden they stopped working just one day. I was told to reinstall Windows, so I installed XP pro.

have you tried more than one device? how about a system restore?

I have tried multiple usb thumb drives, cameras, external hard drives, and usb mouse. None work. I have made sre that USB controller is turned on in the BIOS as well.
