I have a Creative MP3 player, recently it quit being seen as another drive-not noted by XP at all. I have tried other USB sticks and they are not seen either, although any device which has own power supply-camra/printer/cable modems are fine.
I have checked on another comp and MP3 player works fine. Any Ideas?
TIA

It's a common problem with USB mass storage devices (which includes
digital cameras). The solution I find most effective requires editing
the registry.
If you go to http://www.experts-exchange.com/Hardware/Q_20790258.html
there's an MS support text which addresses the issue for the case of a
camera but may work for you as well. I've pasted it below between rows of ====. Step 3 is my usual solution.
=======================================================================
Thank you for your reply. According to the information, I recommend you
follow these steps to resolve this issue:
Step 1: Remove Hidden Devices
1. Click Start. Click Run. Type cmd and press OK.
2. Type "set DEVMGR_SHOW_DETAILS=1" (without quotation marks) and press
Enter.
3. Type "set DEVMGR_SHOW_NONPRESENT_DEVICES=1" (without quotation marks)
and Press Enter.
4. Type "start devmgmt.msc" (without quotation marks) and click press Enter.
5. Click View. Click Show hidden devices.
6. Click "+" to expand Imaging devices, Unknown devices and USB devices.
7. Are there any digital camera devices and unknown devices (including
grayed out devices)? If so, please right click it and click Uninstall.
Step 2: Remove all oem*.inf files
=========================
1. Click start and click run then under the run line type in the command
"cmd" (without the quotation marks)
2. In the command line, type in the following (without the quotes) and
press enter after each command:
"cd \windows\inf"
"ren infcache.1 *.old"
"ren oem*.inf *.old"
"del C:\windows\setupapi.log"
"exit"
Step 3: Removing all entries under HKEY_LOCAL_MACHINE/Enum/USB that
start with VID
==================================================================
Removing the VID entries from the registry will cause them to be
redetected at restart.
CAUTION: If you have a USB keyboard or mouse, do not remove the VID
entry for these devices, otherwise, Windows may not restart correctly.
1. Click Start and click Run. Type regedit and click OK. The Registry
Editor window will open.
2. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB.
3. Highlight and delete all the VID_.... entries.
Permissions may be set allowing the deletion of the VID_ entries by
following the steps below:
a) Right-click the key to be deleted, and then click Permissions.
The VID_... Permissions window will open.
b) With Everyone highlighted in the Group or User name section,
select Full Control in the Permissions section.
c) Click Apply, and then click OK.
4. Turn off the computer.
Step 4: Reconnect the digital camera to the computer system:
=============================
1. With the computer system turned off, reconnect the device to the
USB port.
2. Restart the computer.
3. After the Windows operating system has finished restarting, plug
the digital camera into the electrical outlet.
4. A New Hardware Detected window should open and reload the drivers.
If the camera still cannot work, I recommend you plug the camera to
another Windows XP computer (Desktop) to test whether this camera works.
I suspect it is an incompatibility issue.
