Hi,

Have tried installing the CHIPSET Driver for the Motherboard?

Check the device manager for any bang on the devices meaning either a driver is missing or a wrong or incorrect driver is possibly installed, unless a REX "x" is foung beside USB hub then that would mean that is it busted or damaged.

but it is unlikely to have a USB hub/port to be busted unless physically, install the chipset driver and check again make sure you restart the system after installing the CHIPSET driver to make sure that it is properly installed in Windows and that it will detect the USB ports in device manager.

The USB ports at the back of the display don't work


If all cables are connected properly, this might be a driver problem.

I cannot get my keyboard or my mouse to work with my dell computer. what can i do?


Please add more information to get specific assistance. Are these wireless devices? If wired, do they use USB or PS/2 connections.

For wireless devices, try replacing the batteries and resynching to the receiver. (You may want to check putting the receiver in different USB ports.)

For wired devices, disconnect and reconnect. For PS/2 devices, you will need to restart the computer to check if the devices work. For USB devices, try connecting to different USB ports.

Next step, try using a different keyboard and mouse (that work on another computer (stick to USB or PS/2 to match the current pair)). Try a wired set if the problem is with a wireless pair. If those work, continue diagnostics on the wireless keyboard and mouse. Check if the mouse and keyboard work on another computer. If they don't work with another computer, replace them.

If another USB keyboard and mouse pair don't work in any port, your USB ports may have failed. Check if even one port works enough to access the Device Manager. (Start > Control Panel > Hardware and Sound > Device Manager (Win7); similar directions in other versions of Windows) Check for a problem with the drivers (For USB ports, scroll down to the USB drivers and look for a triangle with a yellow exclamation point or red x). Try to update the driver or roll it back. If that doesn't help and one USB port works, a USB hub may solve the problem.

Otherwise if the USB or PS/2 ports do not work with any devices and the driver fix doesn't work, then I'd suspect a problem with the ports on the motherboard. Replace the motherboard/computer.

I hope this helps.

Try to plug your phone to other USB port in your PC I will recommend to plug it at the USB port at the back of your CPU. USB supply of power at the back of the CPU is sufficient to make your device function properly so it may be able to detect by the system..mostly device can't recognize by the system because they didn't function properly specially if they are plugged in a USB port who don't have enough supply of power to make them work properly..Hope it may help you..

My netgear usb adapter is not working properly and gives error of unsupported operation attempted.please give me some solution


You will need to change the USB port that connects the Adaper to see if the port is working properly or not. If the USB port is working properly then try to re-set the Adapter with the installation disk that came in with it.

Usb ports not working


Check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.

Also check HP's support section on the web for any updated drivers especially for your laptops motherboard / bios

Any exclamation marks by hardware need fixing before you investigate any further
Once you have done that try some of the common fixes below.

I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port
