When I plug in my camera or ipod nothing happens

I go to the device manager and the system controlers and the root hubs all show that they are working properly but they do not show that I have plugged in anything.

    if you have any working device connected to the system try to connect the ipod or the camera in that port and see if that gets detected ... if no than try install the drivers again with the motherboard cd and if that doesnt work try to reload windows and if still that doesnt work last option is to update the firmware of the motherboard that is the bios ... but you need to be carefull about tha... one mistake and you loose the motherboard and than follow the instrucctions on the readme file which you will get with the firmware if that doesnt work that means mortherboard gone bad you can add pci cards which will have usb ports ... or you can change the motherboard

Hitachi touro desk dx3 1tb drops signal from computer continuously


USB ports were brought about in an attempt to standardize how we plug devices into a computer. Computer mice, keyboards, digital cameras, and many other electronic devices now utilize an USB port connection. A port that is not functioning as expected can be mission critical, or an infuriating annoyance at the least. A port that continuously turns off and on may not be broken, this maybe a "Power Management" feature of the device. USB ports can hibernate just as a computer or laptop do. If it's dozing off is not in your best interest, you can disable this feature.

Open "Start Menu", select "Settings", then menu item "Control Panel." In "Control Panel" window click open the "System" icon. When the "System Properties" box opens, select the "Hardware" tab, then click the "Device Manager" button. When "Device Manager" opens, click the at "Universal Serial Bus Controllers" to expand it. Right-click the first "USB Root Hub" item and select "Properties" from the menu. Select the "Power Management" tab. Clear the checkmark from Allow the computer to turn off this device to save power. Click "OK." Repeat these steps for all the "USB Root Hubs."
