I am assuming that there are other USB ports on your notebook that are working and that all of them are occupied. If this is correct, you can purchase a USB hub that will expand a single USB port on your notebook to a larger number of ports. You may need to have a powered hub depending on the devices that you are connecting. USB hubs are not expensive (under $10). Hard drives, CD/DVDs and other power users will probably require a powered hub.

An example of a USB hub can be found at: http://3btech.net/sublfopopous.html

This is not a product recommendation, but an example of what a hub is and how it could help your situation. You can find many other choices by searching for "USB hub".

It is also possible that your USB port has become disabled and needs to be re-enabled through Windows. Look at CONTROL PANEL; SYSTEM; DEVICE MANAGER; UNIVERSAL SERIAL BUS CONTROLLERS. Then examine each one listed to verify that the system thinks they are working correctly. If not, you can take appropriate action from the tabs on that window.

Usb port can't work


Hi,
There are basically 2 reasons why USB ports will not work besides being faulty.
1. The drivers are not installed (inf files)
2. The ports on certain motherboards can be disabled in the CMOS or BIOS setup.

To check if the USB drivers are installed you can open control panel>device manager. Scroll down to "Universal serial bus controllers and make certain these are present and installed correctly.

Also make sure your USB device is functioning properly by plugging in to a USB port on a different computer.

Please let me know if you need any further assistance.
Best wishes,
Graemevm

Usb ports not working


If all the USB ports are not working, this indicates that the USB controller circuitry on the motherboard has gone faulty. If you can however get one port working, you would be able to use an expansion card with usb ports. To rectify the USB controller problem, you would need to have the laptop checked by a technician to trace where the fault lies.

Hi, the ethernet port located in the back of my computer appears to be faulty. I am unable to connect to a modem/router successfully due to this problem, also my USB ports don't appear to be working. Can...


If your lan card is faukty then you have to replace the LAN card. But as regards the USB ports not functioning the best thing to do is to install the usb drivers for your PC. When you install the USB port drivers for the PC the PC will be able to accept plug and play USB internet modems.
The drivers for your usb port can be located when you go to device manager select USB ports and it will take you to the drivers for the ports.
Hope this solution has been helpful?

My magic jack could not work with my vista home premium desk top computer


In what way would it not work?
You may have a faulty USB port or may be disabled in the system BIOS. Check for USB port functionality first since magic jack uses the USB port.
Get ahold of a flash-drive and see if the flash drive works in the port. You may have a faulty magic jack device if nothing else.

Whenever I insert my pen drive into my pc,it restarts computer. what is the problem ?


if this is only happening on 1 usb port, there is a short in that port that is causing you PC to shut down. Your motherboard BIOS is probably set to reboot on power loss which means it will boot right back up if it shorts out.

If it happens on every USB port then your pen drive is faulty and I would refrain from inserting it anymore before you damage your hardware.

If the pen drive works on someone elses computer, then it sounds like the SOUTHBRIDGE chip (chip on motherboard that controls USB, PCI slots, firewire ports, etc) is going bad or is faulty.

Problem with my Dell Inspiron 5160 USB port


This is either a driver glitch or a faulty port. Start by uninstalling the usb drivers from the device manager, then reboot. The machine will find the ports and reinstall the drivers automatically. If this doesn't fix it, then the ports are faulty and will need replaced. The usb ports are very simple devices, when the drivers are present, they either work or they don't. Other than the drivers, they have nothing else to go bad other than the port itself, and in general, when one goes they all go.
