Help, I have tried various USB stroage devices (including
Memory Pens and Multi Card Readers) but cannot get access
to them. When they are plugged in, there is some
recognition as they appear in Device Manager under both
USB Serial Controller and Disk Drives. In addition they
appear in the 'Safely Remove Hardware' section under PnP
in the System Icon BUT nowhere in any program. I cannot
see them under Explorer or under the My Computer section
or any other option. Please advise how I can get these to
appear and be accessed under the 'normal' bits of XP.

Thanks

I hope you get an answer because it sounds exactly like
the problem I posted yesterday:

Can you let me know when you figure this out, because I,
too am having the same problem. I'm running XP on a Dell
Optiplex 260.

Thanks,

The problem is on my home system (I am currently at
work). When I get home tonight I am going to try some of
the ideas on the website:

Thanks, let me know what you find.

I figured it out. I had a netword drive mapped as E: I
disconnected the mapped drive, rebooted, and now my USB

hat gives me one idea to try. When I first set up the
system on Saturday, I had three physical hard drives,
each with two partitions (my original 2 IDE drives and my
new S-ATA drive). They mapped at C-F, D-G, E-H. I also
had two CD drives, I and J. After I copied my data off of
the old E-H to the new C-F, I removed the original 2nd
IDE drive and now I had C-E, D-F. The CD drives stayed at
I,J so I then changed their assignments to G and H. The
camera or Sandisk, whichever I plug in, tries to map to
I:. Maybe that old letter has some left over vestige of
the CD. I will try moving the CD back to I: and seeing
what happens. I don't have alot of hope, but it's
something!

I am having the same problem using XP home with one
extrenal harddrive, however my problem is that for 20
months it worked,now it won't but it is listed in device
manager and I have reinstalled the drivers and got the
message about finding new hardware, but it doesn't
recognize it properly, it says the door is open.

By any chance, do any of your motherboards
support USB Mass Storage devices?

And if it does, is the option for USB
Mass Storage device in the BIOS?

I use the ASUS P4P800, which has
the option in BIOS. I wonder if the mobo/BIOS
would have to have the option, before you
can use a USB Mass Storage Device?

I use a Apacer 7-1 card reader (USB2) internal
which XP picks up as a Mass Storage Device
no probs at all. And gives me 4 extra removable
devices (I,J,K,L). I've just replaced the floppy
with this, as you can also boot from the card
reader, by the looks of it.

Which can can take the SD/CF/MD/MMC
Smartmedia, MS and MS PRO cards.

I use it with a digital camera, which uses
an SD card, with no probs at all.

I have the ASUS P4C800E-Deluxe. It does have BIOS setting
related to usb mass storage devices, but they seem to be
for permanent devices that are present at boot. They
don't seem to be for removable devices, like my SANDISK 6-
in-1 card reader, Sony camera, or USB flash card (all of
which don't work).

I noticed another interesting thing last night. I ran the
Management Console/Disk Management utility while I
plugged in the devices. They showed up with letters for
30 seconds or so before they disappeared. Even while
showing in Disk Management, however, they did not appear
in Explorer. After 30 seconds they disappeared and the
new hardware utility reported a failure installing a new
device.

This is very strange and I would sure appreciate if one
of the MVPs would jump in with some advise!

My idea didn't help, even when I moved the CDs up to
X/Y.

Waiting now for some MVP help!

That sounds right Stan. This reader is permanent
you could say. As it's connected to a USB2 header
on the mobo. And is internal.

And DOES run as soon I turn the
computer on (It has a power, and an access light)
so you know when NOT to take a card out of it).

It might have to do with certain updates as well.

I dont know.?

This is getting stranger.

I looked in the USB section of the BIOS last night. I
found it displays the number of currently active USB
devices, and would show the hub plus 1 or 2 drives,
depending on what was plugged in. BTW, it makes no
difference whether the failing devices are plugged into
the hub or directly into the motherboard. The BIOS
settings were related to post delay time, how to handle
USB 2.0, etc. and appeared to be unrelated to the problem
at hand.

I then booted back into XP, and low-and-behold, the
camera and SANDISK were working. The flash disk card was
not. Then, with no changes, the SANDISK stopped working
again. Periodically the system would freeze up until I
unplugged the cable.

I will probably end up doing a repair install of XP, but
after only 4 days I shouldn't have to do that.

Would sure like to hear from an MVP . . .

Hmmm how many watts is your power
supply? If you are running too many things
on a well 250-320/350 p/s. It maybe draining
the power needed for USB. Unless you use
a powered hub (which I see u have, by the
looks of it). BUT how many of your USB
devices are plugged into the hub?

All, or 1?? And how many things inside
the case? ie: hdd's / cd's burners etc.

have a 275 Watt PS. The devices are plugged into a
Dlink USB 2.0, high speed 7 port powered hub. In the case
are:
- ASUS P4C800E-Deluxe MB
- ATI Radeon 8500
- Creative Audigy Platinum
- WD IDE drive
- WD A-ATA drive
- Sony DRU-510A DVD+-RW
- CD-RW drive
- 3 1/2" Floppy

I would be surprised if the problem was power-related,
but I have been surprised in the past!
