After moving my computer from one room to another i have found that my USB ports will not work. I can not get my digital camera to upload pictures or my printer to print. I've tried uninstalling the USB devices and thne having them reinstalled but that has not helped. Can someone help me?

thanks

Short, practical checklist to try next (builds on the answers from and without repeating them).

  • Safety first: shut down and unplug the PC, discharge static, then open the case. Inspect the motherboard area around the USB connectors and the cable that runs from the front-panel USB jack to the motherboard. Reseat that header cable (or the rear I/O if your ports are soldered there) and look for bent pins, broken plastic, or cold solder joints that might have been stressed during the move.

  • Check firmware settings: reboot into the BIOS/UEFI and confirm the on‑board USB controller is enabled (and legacy/USB support options are sensible). If unsure, try “Load defaults” and save, then retest.

  • OS isolation: if the OS never shows a device when you plug it in, try booting from a live CD/DVD (Linux or Windows PE) to see whether the ports work outside Windows. If they work from the live media, the problem is drivers/settings in Windows; if they don’t, it’s almost certainly hardware.

  • Clean Device Manager of ghost entries before reinstallation: open a command prompt and run

    set devmgr_show_nonpresent_devices=1
start devmgmt.msc

    then in Device Manager choose View → Show hidden devices and uninstall any greyed-out USB controller/Hub entries, reboot, and let the system redetect hardware.

  • Quick checks: try a simple bus-powered USB device (keyboard/mouse) and a self-powered USB hub if available; check Services (Plug and Play) and the system Event Log for USB/PnP errors.

If none of the above isolates it, the likely causes are a damaged USB controller or motherboard trace; a cheap PCI/PCIe USB card is an inexpensive way to confirm and restore USB without replacing the motherboard.

does the pc detect that a device has been pluged in when you insert the camera? if yes then will have a go if no, what type of usb? usb2 or 1.1 is it onboard or a front pannel header or a pci card?

are you using the same usb socket? do you need to have a power supply to camera?

the computer does not detect that the devices have been plugged in. I'm not sure how to tell if it's a usb2 or a 1.1, it is onboard and im using the same socket. And no i power supply for the camera is not needed.

*

WinXP by Default turns off USB Root Hubs to Conserve Power causing some devices not to resume correctly after Windows resumes from sleep, hibernation or computer inactivity
*

In the Device Manager > Universal Serial Bus Controllers > USB Root Hub > Power Management, Uncheck the box per the illustration below. Uncheck all boxes on all root hubs.

Allow the computer to turn off this device to conserve power.
