USB Flash drive problems

Everybody seems to be having problems with USB drives today !!

I have a Dell Dimension 5150C with XP including SP3. Until recently, I
had no problems using flash drives. They showed up as another drive - E
or F. Then last week I found when I plugged in a flash drive - no
response. It no longer showed up as another drive. I tried in several
USB ports. No response. I tried 3 different flash drives. No
response. But all three work on my other two computers - a lap-top with
XP and a new Dell Inspiron Desktop with Vista.
Furthermore the USB slots show no problems when I plug in other devices
- printers or a floppy disc drive.
Does anyone know what the problem could be ?
Device Manager gives no help. It shows no problems with USB ports,
although I don't know which one is which on Device Manager.

Hi Stuart,

What make and size is the USB flash drive??

Are you plugging this into a front or rear port or are you using a USB Hub?

Try leaving the flash drive plugged in and turning off the computer and
restarting and see what happens.

Have you checked your power supply?
 
Thanks for the prompt reply.

I have 3 flash drives. The smallest - 16MB - I bought from Dell with
the computer 3 years ago. (At that time 16MB was considered big !) The
other two are each 2GB. One is from PConKey. Don't know who they are.
The other I got free after a stay at a hotel in Barbados. All three
work fine for what I use them for - transferring data between computers.

I have tried USBs at the front, the back and from a USB Hub. No
recognition. I don't think I have tried them in every slot.

I have tried leaving one in a USB slot, then shutting down and
restsrting. No recognition.

I don't know quite what you mean about checking the power supply. It is
very reliable and not overloaded.

Thanks for your help. Any other ideas ?

Disconnect all "flash" drives

Create a "batch" file with the following:
------------------------------------------------------------

set devmgr_show_nonpresent_devices=1
cd %SystemRoot%\System32
start devmgmt.msc

------------------------------------------------------------

Run it and check select "Show hidden device...."

If you have a list of "unknown" devices section, uninstall" all.

Under Universal Serial Device section, uninstall every "unknown"
devices.

Then, try to conenct on flash drive. XP "should re-detect" it.

Select Start, Control Panel, Administrative Tools, Services and right click
on Plug and Play and select Properties. The StartUp type should be
Automatic. Is
it? Has the service started?

The problem is probably the HP printer has card reader ports which are using
all you assigned drive letters. To verify this is the problem unplug the HP
printer from the USB port and then reboot and try you other devices and they
should work. This is a know issue with HP photo printers that have built in
memory card readers.

Hope this helps,

Thanks and sorry for the delay in replying.

Yes Plug And Play/StartUp type is "automatic".

Stuart
 
Have tried the batch file as you suggest, but no "Unknown devices"

Everything looks very normal

Stuart
 
Thanks Deejaydee

I tried updating the drivers for all usb devices but they all reported
there was nothing newer than the installed driver.

Stuart
 
Thanks but I don't have a HP printer. I have a Brother MFC attached
wirelessly but it doesn't take Drive letters for its card reader ports,
as far as I know.

Stuart
 
I want to thank all those who jumped in with suggestions/recommendations
although none of them solved the problem.

By chance I was looking at a Swiss-German monthly, Online PC Zeitung,
and saw a reader's query about USB sticks no longer starting
automatically. He was recommended to download from microsoft.com the
Autoplay Repair Wizard and run it.

It is a bit difficult to find in /Downloads/ but I got it, ran it and -
Hey Presto - problem solved. The sticks now show in My Computer when
inserted and don't show when removed. I had fixed the USB properties to
NOT require the use of Safely Remove Hardware.
