USB not recognizin device

[JEFF]

I recently had to reinstall XP on my PC, have done all the updates and am
running SP3. Whenever I plug anything(triied a flash drive and a
wirelessadapter) into my USB Ports its not being recognized. I have
installed the drivers for the wireless adapter already.. Can anybody help
explain why the USB ports aren't recognizing devices??

You say you "installed the drivers for the wireless adapter" but have you
installed the motherboard maker's drivers? These are what makes the USB
ports work and they are needed before the wireless software can do anything
useful. You should have received a CD (or floppy if the computer is ancient
enough) from the maker with the required drivers. Or, lacking that, you can
probably download them from the manufacturer's website.

If you feel like poking around in the computer, there is a neat free
utility program from http://www.nirsoft.net called USBDeview which reveals
everything the computer knows about its own USB ports and devices, down to
a list of everything that has ever been plugged into a USB port.

Hi Jeff,

Reinstall the chipset driver package for your make/model system.

These USB ports and devices all worked before, yes?

If you right click the desktop My Computer icon, choose Properties,
click the Hardware tab, then Device Manager, do you see any question
marks, red x's, yellow things, - anything that looks like it might be
wrong?

Then expand the Universal Serial Bus controller section at the bottom
of the list and see what that looks like (any errors). BTW - If you
don't see the word Enhanced down there, you are going to have another
problem later but check this part out first.

Does XP just not do anything at all or does XP say the the device is
not recognized?

Did you try all the USB ports?

My wireless adapter (and some devices) get power from the USB port.
My adapter lights up when plugged in. How about your stuff? Do you
have another computer to see if your devices are okay?

Try the USB ports directly off the motherboard - not the wired ones
that might be up front. One guy I know complained about this problem
and he forgot to wire up the front ports - duh.

Thank you for the tip....Once I downloaded an updated USB Driver for the
machine everything worked perfectly...Thanks again.

Hi there.

I have a Sony Cyber-shot DSC-W50. When I purchased it a couple of years ago,
the instructions state that I did not need it use the installation disk for
the USB drivers because if I use Windows XP, the drivers were already a part
of the standard Windows pack. I have had no problems using the cable supplied
with the camera to download pictures via USB drive up until recently, now the
device is not recognized.

I have followed all the various troubleshooting suggestions in the Help
files, removed and reinstalled USB Hubs used the disk that came with the
camera (both with the Wizard and without, it doesn't recognize any of the
files on the disk as related to the camera), checked the Sony site for
updates (there are none), read the support article on the Microsoft site (the
only suggestion was making sure I have Service Pack three, which I do).

I tried on my work laptop with XP, and a friend's work PC with Vista, the
device is still not recognized.

The device is not listed on the Windows XP Hardware Compatibility List, if
that indicates anything.

I've found some Web sites with free drivers, but that makes me nervous as
I'm unsure of the source.

I'm at the end of my rope, ANY help would be much appreciated!

Have you tried a "memory stick duo" external memory plugged into the camera ?
Could it be, that there is an internal memory failure ? Can you "check
the plumbing" with an external memory plugged in ?

If you run UVCView, does any USB entry show up for the camera ?

This is what a visible device might look like.

There can be varying levels of response from a USB device. For example,
there can be a failure to "open communications pipes" with the device.
But to start, see if there is any response at all. At least that
might tell you whether the USB interface is busted.

Since SP1, Microsoft has provided USB 1.1 and USB 2.0 drivers.
They include USB class stacks, for things like USB Mass Storage.
Something that might not be provided by the standard USB offering,
is MTP (an alternative used by music players, and has more
DRM capabilities).

I would not recommend scrounging around for USB drivers in some
dark alley. That should come with WinXP, in a Service Pack.

Your chipset uses a set of drivers, and the main purpose
is to label the elements inside the chipset. If you already
have USB elements listed in Device Manager, chances are
you already have some version of that in place.

This won't work, if the device is truly invisible, and is not
showing up in UVCView. Otherwise, this is a file recovery
program, which searches a device for likely files. It works at
the raw device level (on the assumption the file system, perhaps
a FAT type, is damaged). It may be able to transfer what is on
the camera. If so, you may then be able to reset or reformat the
camera (see camera manual for the manufacturer's recommendations)
and see if that improves the file system situation.

Blindly blasting the storage device in the camera, from Windows,
is not always a good idea. So Google your camera model, to
see if there are any specific gotchas known for the camera.
Some stop working, if the user becomes a bit too creative.
(An example might be, attempting to reformat the device
from Disk Management.)
