Dear Greg.

If you recently or earlier installed any type of Audio or Video Hardware such as an Upgrade. or better equipment than originally come with your Computer, than the New Equipment Nullifys your front USB. You probably have to go to the rear of your computer instead of using the convienient front. If that works than you have to decide is the new equipment worth the inconvienience. Hope this helps,

please rate my service even if its bad, thank you.

also, another tip is to use Fire Fox, thats a Free Bee if you own a portable SanDisk which stores info like a disk. which is probably why you want your USB instead of just Cameras, External Plug Ins, ETC.

Click on the link below and scroll down to the "Fixit" button. This is a patch to enable USB devices. This is a common problem especially after running Windows Update. Good luck.

It wont show up


Have you tried alternate usb cables and usb ports on your system? have you tried a different system? If that doesn't resolve the issue- you have a dead external drive- if swapping the cables works, you have a dead cable. If swapping the port that you are connecting to- it could be the port is bad, or the port is a low power port. If swapping to a second system works- and none of the ports on the other system works- then the system will need service- either for reinstalling windows, or a replacement motherboard since the USB has failed.

I have a 2GB Kingston USB, and never detected when i insert to the USB port, my problem is, how can I reformat the USB? I hope you can help me to solve this problem. thanks and more power.


Have you tried the other USB ports? If none works, try also a different USB device to the computer. It may be that the USB drive you have is the one defective. If another device isnt detected as well, try updating your chipset driver, and also reset your BIOS to default. If none would work, possible motherboard replacement will resolve the issue.

The USB ports on my Toshiba A135 S2356 laptop are not working. I tried to use my printer and it says not connected. I bought a new cord but it still doesn't work. What should I do?


1. first check ur USB port using any other USB device, like pen drive, mouse, keyboard,etc.
if system detects that device, then ur USB port is OK!

2. if USB is OK, then the problem is with the 'Printer Driver' not the cord!

3. reinstall the printer driver!

4. update the driver!

5. if USB port is not working, then replace it!

if this helps, tell me.......

USB PORTS


does your usb mem stick have any light indicators? if yes , whenever you put you usb stick, does it light? if it lights are USB ports is still ok,  You just have to reformat or partition you USB stick.
(you can also try other devices like usb mouse or any usb devices that lights up when you connect it)

if there are no lights if you plug, or no indication that a power goes to your stick, its possible that your usb your are busted. if this is the case, if your laptop has a PCMIA slot, you can find a pcmia USB card, if you dont have. your only option is replace the  motherboard.

Compaq Presario v2000 w/ dead USB ports


Does 1 Usb port work on your computer? Sometimes they can go out. Do you have a USB hub you can use?

USB


First of all, I recommend you to Uninstall the USB Devices from the Device Manager and reinstall the Chipset Drivers as per the instructions below :
Click on Start and then on Run.
Type devmgmt.msc in the Run Command box and click on OK.
This will open the Device Manager window.
In this, click on the + mark next to Universal Serial Bus Controllers which will display additional USB Entries.
Right click on each of the entry and select Uninstall.
Click on OK if you get any confirmation window. Repeate the same process untill there are no entries left under Universal Serial Bus Controllers in the Device Manager window.
We are done with uninstalling the USB Drivers from the Notebook.

Now, restart the Notebook and close any window which says 'Found new hardware'

Now, download and install the Chipset Driver in your Notebook from the link below :
http://downloadmirror.intel.com/8178/a08/infinst_autol.exe

Save the file in the Notebook and double click to install the Chipset Drivers.
However, if the issue with the USB Ports persists, I recommend you to check again with different devices to confirm if the issue is with the USB Ports of the Notebook itself.
If the Notebook doesnot recognize any of the USB Devices after installing the Chipset Drivers, you may need to get the USB Ports of the Notebook replaced or go with a PCMCIA USB Card.
Hope this helps....

Usb ports not picking up memory stick


Is it just Memory Stick, or everything that you plug into USB?
Try following:
  1. plug in other USB device into ports
  2. if it does not detect any USB device on any port on your computer
  3. if both front and back USB do not work it may be taht USB is turned off in BIOS, or USB driver is corupted
  4. If you have front USBs and they just do not work there is wire connecting them to the motherboard since it may be loose, if connection is OK than they are dead.
  5. If just back USB do not work than they are dead>

My D820 USB ports are not functioning properly


Try reinstalling the drivers for the USB by going to device manager.Just uninstall the usb hub drivers and restart the system.Once you restart it, it will reinstall the drivers on its own.Inacse this does not work you would have to get the ports replaced by getting the motherboard replaced

Usb


Check ports are operating correctly, go to Control panel>performance & maintanace>admin tools>services. Look dow list for 'plug and play', make sure this is set at automatic, the furthur down list 'Universal plug & Play' and ensure this is set at Manual. if all is ok then it may be a usb power issue if you ave lots of hungry usb peripherals, try disconnecting some and try your problem periheral in a different usb port.
