XP dosn't see USB

By GGDeal ·
My Pentium III 366mhz, 512mb ram, 30gb hdd, with I recently loaded WinXp, all was fine for the MOST part, however recently system does not recoinize any of my devices connected via USB ports, I have a USB visioneer 4400 scanner that was working fine, thank you very much, and now not only does the system not reconize my scanner, but my ms usb track ball dosn't work either or my usb connected pc flash card reader.

I disconnected the track ball and card reader in an attempt to see if they were'draging down' the signal, but that didn't work.

Should I try to reload winXp pro?

XP dosn't see USB

Bandwidth on the USB can be an important issue for troubleshooting. Devices can be added to the USB without concern for how much bandwidth may be used at any one time. Problems arise when a device intermittently becomes unavailable or has other availability issues. The tool supplied in Millennium Edition to help troubleshoot this type of issue is the Bandwidth Usage Tool. To check the bandwidth usage of each device connected to a Host USB controller, use the Device Manager tab to navigate to the Universal Serial Bus Host Controller entry.

Select the USB Host Controller and click Properties for that device to view information about the USB Host Controller and the USB Root Hub.
Select the Advanced tab to access Bandwidth Usage. The General tab contains basic information about the USB Host Controller.

The option to Disable USB error detection on the Advanced tab simply disables the error message dialog boxes. These errors concern bandwidth issues. One scenario in which bandwidthcould be an issue is if a USB camera and USB speakers are operating at the same time. If functionality is not impaired, disable detection of these errors.
"Bandwidth Usage" displays the Advanced dialog box with bandwidth information about each device.

Each USB controller has a fixed amount of bandwidth. All devices attached to the controller must share this bandwidth. The Bandwidth Usage dialog box displays the bandwidth distribution among all the connected devices that are attached to this controller. Select a device from the list box to see the amount of bandwidth that the device uses in the Bandwidth Indicator bar box.
If the indicator shows a full bar for one device or if several devices add up to a full bar and there are stilldevices left, this could indicate the problem. The solution is to add an additional USB Host controller to the system and move some devices over to the new controller.
