First, please disconnect all USB devices and then perform the following steps:


Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.



In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".



Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".



Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.


for xp or earlier


click start right click on computer select properties device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X


you will need to update/reinstall drivers

right click to reinstall drivers


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



Hope it helps.

SOURCE: My drive has been working

Try to scan your Had Drive with updated anti virus it may attacked by a virus. Connect it again where the hard drive is working fine. I have some clarification if you disconnect it properly in the computer where you have the time you use it. Because if you disconnect it in your PC without proper procedure it may possible cause of corrupting you files inside you hard drive or internal damage to your hard drive.

SOURCE: My hard drive don't work in the USB port on my toshiba 26el800a tv

this toshiba tv only supports harddrives that are formatted in FAT32 format.
you will need to reformat your hard drive to FAT32 in order to display pictures and play audio.
there is no other support for movies etc according to toshiba's websitehttp://www.mytoshiba.com.au/products/televisions/led-backlit-tv/el800a/26el800a/specifications#details

Hi my wireless keyboard & mouse do not work at all on my Acer Aspire M3970, but both a cable keyboard & mouse do?


There is a USB receiver underneath the battery panel of the mouse, although it looks like part of the workings of the mouse. It's only a very small thing with a USB plug on it but it is there. The instructions don't show a picture of it, so it's very easy to think you haven't got one until you look closely

Unclip it and put it in your USB port and it should come up.

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.

I just got the mp3 player. ive been charging it but when i disconnect it from my computer it shuts off and wont turn back on. HELP!


Some older computers that have USB ports that limit the output to 5V @ .5 amp current. Depending on your MP3 player, it may not be sufficient to charge the player. This was the spec back then. Since then, new USB specs call for 5V @ 1.0 amp current - a two fold increase in current.

You may have better luck connecting to a powered USB hub instead. If you're only looking to charge the MP3 player, you don't even need to connect it to the computer. The powered hub gets powered by connecting the ac adapter / power supply to a wall outlet - instead from of the computer's power supply via mother board.

The above assumes there is a good, rechargeable battery; a functioning charger & USB port in the MP3 player and of course, a working USB cable. If any of the above is faulty, you'll never get the MP3 Player to accept a charge. You should try different computers, cables and ports if possible.

Good luck!

My acer Aspire 57342 usb port seems broke. How do I get it fixed. I have an air card in the rear port but the front port I can't plug my mouse or printer into. Also another question are both usb...


BAD News.
Usually the USB Port is a part of the Mother Board on a PC and the replacement of the Mother Board is the only solution.
You can find them on the internet at Ebay and other locations. BUT it is very involved to replace.

If you have one good USB Port, Get an adapter that will allow multiple inputs.

Example:

I have a general lee cb with a 4-pin standard mic. the wires in my mic cord broke at the plug. does wnyone know how to wire this type of mic back and what color wires go to the correct pin?there are 6...


Here are the Pin outs for different mics that will work with your radio. If a wire is not listed then you cut it off. It's best to keep the wires as short as possible no longer than a half inch is suggested. Normally the Cobra pin out is standard for most radios.

Stock - 1- Shield (Ground) 2- Yellow (Audio) 3- Red (Transmit) 4- White (Receive)

Astatic - (4 wire) 1- Shield 2- White 3- Red 4- Black

Astatic - (6 wire) 1- Shield & Blue 2- White 3- Red 4- Black Yellow NC

Daiwa EM-500, Cobra, CA Series - 1- Shield & Black 2- Red 3- White 4- Blue

Galaxy DC-521S - (4 wire) 1- Shield 2- Yellow 3- Red 4- Black

Galaxy CB-660EI - 1- Shield & Black 2- White 3- Red 4- Blue

Sadelta - 1- Shield 2- White 3- Brown 4- Green

Turner - 1- Shield & Red 2- White 3- Blue 4- Black Yellow NC

Its showing just blue background on the screen wita mesage NO SIGNAL.


If you are trying to capture from a digital camcorder (tape), you have to use a firewire connection, USB does not work as stated in requirements.
Adding to what Walt said, firewire cables don't connect to a USB port. If you don't have a firewire cable, you need to purchase one. And if you do, don't buy a cheap one. Buy cheap, buy twice.
