USB dosaent recognize portable storage

[Guest]

All of a sudden, windows XP dosen't recognize my portable storage devices
(Maxtor usb hard drive, lexor jump drive or pentax digital camera). Devices
used to work and still work on my lap top. Have tried trouble shooting; have
uninstalled all usb drivers and rebooted several times. Have performed system
restore several times. Constantly get "usb device not recognized" message on
all devices. Can anyone help?

Hi, Peter.

Are any OTHER USB devices recognized? (Printer? Scanner?) Maybe you need
new drivers for your USB controller itself. Is it built into your computer
motherboard, or on a PCI card? Or perhaps an external USB hub that needs to
be powered?

In Device Manager, there are sometimes skeletons hiding in the closet. Be
sure to click View | Show Hidden Devices to be sure some old out-of-date USB
driver is not still hanging around.

Also check the other DM - Disk Management (diskmgmt.msc). This manages much
more than hard disks, including CD/DVD drives, "flash" or "jump" drives,
digital cameras and card readers - just about anything that might be
assigned a "drive" letter and accessed by Windows Explorer.

R.C- Thanks for the comments. The printer and mouse (thankfully) still work
through the USB connection and I am reluctant to un plug them. Also, an old
64m disk-on-key works. However, the Maxtor 80 g hard drive ( which has its
own power), the pentax optio camera, and the Lexar 1g jump drive consistantly
come up as "device not recognized" although they all worked fine for over six
months until the 8th of April. All are plugged directly into the computer ( A
Sony Vio with 8 USB ports) I have run Norton - no virus's. I have
uninstalled all the USB drivers and rebooted. I have checked for new drivers
and Device manager tells me they are the newest version. All the USB ports
say they are working fine until I plug something in and they won't recognize
it. I checked diskmgmt.msc and the USB drives (which used to be drive H and
I) are not listed. Am I missing something?

The USB Mass Storage driver is USBSTOR.SYS. You will also need the inf
files if you have to reinstall it. You can find these drivers at
http://www.usb-drivers.com If you need the usb general drivers you can
get them from http://tinyurl.com/9k5ge you will have to do a free
registration, and it is painless. usbstor should be in the
system32/drivers directory. From post at 'MSFN.ORG'

Treeman,
Thanks. I downloaded and reinstalled all the drivers (maxtor and
usbstor.sys) like you suggested. Still dosen't recognize portable hard drive
or jumpdrive. What am I doing wrong?

Can you go into Drive management and see the external Maxtor?
Right click My Computer, Manage, Disk Management.
If so, you will need to format as a basic drive / ntfs & give it a
drive letter.
Windows may be confused!

Not sure. I deleted all my cookies; ran spybot twice to remove all spyware.
Uninstallsed service pac 2. Unplugged every wire from my computer (mouse,
keyboard, screen, speakers, etc.), then replugged everything in one at a time
and let windows detect it. Now USB ports work fine. Not sure what fixed it.
May have been spyware or a virus, or SP2. Hope it dosen't happen again.
Hope this helps.
