Probably USB port is disabled on the Bios setup. Enable it on the bios setup. Rest will be done automatically.

if you can see your usb drive but its not working
ports (com&lpt) right click update driver if this fails to fix the problem
Check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts Check if USB Ports Are Damaged

USB ports are an important part of your computer's hardware.
Many devices connect to the computer via USB, such as music players, cell phones and digital cameras.
This connection lets you charge your devices and manage files on them.
When you connect a device to a USB port, it is typically recognized automatically.
If not, there may be a problem with the port. USB ports sometimes fail on their own, or they may be damaged by force.

Plug a variety of devices into the USB port you think is damaged.
If none of them work, the port is probably broken.
Connect the same devices to the USB ports on a different computer.
If they work, this is another indication your ports may be damaged.
Run Windows Update on your computer to ensure your devices and computer function together and have the latest drivers.
Click "Start," then type "Update" in the search bar.
Click on "Windows Update," "Check for Updates" and "Install Updates."

Open the Windows Device Manager by clicking "Start," then typing "device manager" into the search bar.
Click the Device Manager link when it appears.
Click on each of your USB ports.
In the Properties window, look for "This device is working properly."
If this is displayed for each USB port, they are not damaged, but there may be a problem with your device instead.
Click "Update Driver" next to each USB port in the Device Manager, and Windows searches for and installs the latest driver.
If one can't be found, go to your computer manufacturer's website, and download the driver there. Try to use the USB port again.
Sometimes, outdated or damaged drivers result in a non-working USB port.

Open your computer case by unscrewing or sliding off the side cover.
Use a can of compressed air to clean out the dust from inside, especially from within the USB ports.
If your USB ports are hooked up to the motherboard, remove the cable, then replace it.
These actions sometimes help to fix non-working ports.

Problem with usb port don`t work


Step 1
Before you start working on the USB port, make sure that your device is not the problem. If the computer says that the there is a new USB device but that it cannot use it, typically there is a problem with the device's driver and not the USB port. If this is the case, your best option is to re-install or upgrade the device driver. Try inserting the device to another computer. If the device works, most likely the problem is with the computer and not your device.

Step 2
Try rebooting the machine. Rebooting a computer resets all of the software to the default state and will clean up many issues. The start up process also checks all of the devices on the computer and can sometimes fix a USB port. First shut down the machine. Connect the USB device up to the computer and start it. This reboot will sometimes fix a bad USB port.

Step 3
Try attaching the USB device on to another USB port on the same computer. If the device now works, the old USB port probably has a hardware or BIOS issue. Skip to step 5 to try to fix a bad USB port through the BIOS. Fixing a hardware problem on a USB port requires working on the motherboard which is typically more expensive just adding a new USB ports.

Step 4
Uninstall your computer's USB device bus manager. The device manager controls the USB access and sometimes gets corrupted. Fixing the USB device manager requires administrator rights on the machine. The best way to uninstall the device bus manager is to right click on your computer's icon and select properties. This will bring up the hardware settings for your machine. Click on the hardware tab and select the device manager. The device manager lists all of the devices on the computer. The next step is to open up the "Universal bus controller" option. Right click on all of the items under this option and uninstall them. Once all of the devices have been removed, restart the machine with the USB device connected. Upon reboot, windows re-installs the USB device manager. Most of the time, this will fix the USB port.

Step 5
The next thing to try is to check the BIOS. Restart the machine and enter the BIOS setup screen. You should check to make sure all of the USB ports are active. If they are, you should try resetting the BIOS settings to the defaults. The BIOS reset will sometimes fix USB port. But if it does not you will have to consider upgrading the BIOS. Upgrading a computer BIOS is very dependent on the motherboard manufacturer and you will have to visit your computer manufacturer's web site for detailed instructions.

Step 6
The last trick to try to fix a USB port is to repair your OS. Sometimes the USB drivers can get corrupted and break the USB ports. You can reinstall the system files onto the computer which should fix the USB port. Your data files should not be changed in this process, but it is a good idea to do a full backup of the computer ahead of time. In windows, an OS re-install is done by loading up the windows installation CD/DVD and selecting the repair windows installation. Just follow the steps and you often have a fixed USB port at the end of the process.

Please rate me if this solution works for you

Thanks......Have a great time.

USB Driver/Hardwa


Hello rkalmus,

You may need to update your USB devices. The best way to do that would be to have the CD driver for your motherboard.

Once you have the CD driver, just insert it to your CD or DVD ROM, go to your Device Manger, right click & choose update.

If you have more follow up questions, send me an email to artpena789@yahoo.com.

Hope that helps & best of luck!

Usb not found aspire t160


Hi,

i,d check the bios setup. to ensure that USB devices are enabled.
Or that there are no conflicting devices:- My Computer/Control Panel/System/Device Manager.
Also some motherboards, have jumpers to set the USB ports on/off.
Try using a different port if you have 1 available, or purchase an individual PCI-Card with USB Ports On.
