USB device does not work

Check your device manager and verify you have the enhanced host controller installed in the USB device of the computer. If not, consult with the MFR of your computer online and download the driver.

YOU HAVE TO INSTALL DRIVER BEFORE YOU HOOK THE USB CABLE.

reinstall the USB drive with USB 2.0 drivers and will work

try downloading the drivers from sony first http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&externalId=C116935&fes=true&mdl=DSCW5 that is if you have already downloaded the proper usb drivers for your system in which case other usb device are still working also it is possible that the usb port itself has gone bad or is in conflict with another driver assuming your using windows to check this you can start by telling me which version of windows you are using but more than likely the proper camera drivers will solve the issue

I have had problems in the past with some Mp3 players including Ipod and Iphones not recognized by some motherboards and I found that even with the latest drivers not all USB plugs work as they should be, either USB 1 or USB 2, for example recently in my ASUS motherboard, (though my ASUS mobo is a few years old) it does have USB 2 but my Ipod and my sister's Iphone were not recognized by it and what I did was to buy a USB card with a couple of external connectors and I installed this in my PC and installed the Windows XP drivers that came with it. When I pluged my Ipod and my sister Iphone they were recognized inmediately and they have not given me a problem ever since. You know, what happened is that even though this card is just another USB 2 connector card it's manufactured by somebody different than the motherboard maker and it has different drivers. For one reason or another my Ipods and my sister Iphone were not recognized by my mobo and it's USB drivers even though most other USB 2 devices work without a problem. Those USB 2 cards are very cheap now, you can get them for about $8 to $12 in some places and that may solve your problems. I'm not saying that this is a sure fire way of solving the problem cause there may be other reasons but for a lot of people this can work and they wont have to go crazy wondering if their devices are damaged, if that's the case they can go to the store and ask for a replacement or have them fixed by the factory but before doing that it may be wise to check if your device is recognized by somebody elses computer first, if that's the case then this may be a solution for you.

please update the USB Drivers and if that Doesnot Work then Update the BIOS of you Computer from the Manufacturers Web site

What is the Pc doing that shows you it is not recognizing the camera?
Have you looked in My computer at your drives to see if it is showing there? For some reason mine sometimes shows up my F drive instead of my camera drive. Then you can just click on the drive and open the folder for the photos.

In this case try to format the Mp3 player with the FAT file system and that should work

Dbl click on "my computer" desktop icon and see what you have listed before you hook it up then dbl click again after you hook it up,,,see if there is anything new listed there,,,if so then that should be the MP3 even though it may not say MP3.Mine says Mass Storage.If its there then just double click that drive and you should be able to drag and drop.

Go to device manager. Remove all USB ports. Re-boot. See if that workds.
