Internal USB flash card reader problem

[Sam]

<I'm resending this, since the first one got sort of messed up>

Sometime in the last month or 6 weeks (I didn't notice exactly when it
happened) I lost the function of my internal USB flash 9-1 card reader.
Windows sort-of recognizes that it's there, and if I unplug it and replug
in the USB cable, I can hear and see it trying to recognize it. The unit
itself is OK, since I can plug it into another computer and it works
perfectly. Another wrinkle is that I can plug in a SANDisk external USB
flash compact flash card reader (single card type of device) and it sees
this device just fine.

I tried another internal flash card reader and it does the same thing... so
at least it's being consistent. In the Device Manager I can see the items
in the Human Interface Devices section (HID-compliant consumer control
device). Even with a flash card inserted, there's nothing in the My
Computer / Removal Storage area (or anywhere else). I've installed any
drivers, but it doesn't make any difference. I also tried removing a number
of other USB devices to see if that would make a difference, in case of a
conflict... so far nothing works. There's a long stretch of unused drive
letters from E through L for the item to use (it used to show 4 separate
drive letters).

I assume that I installed something that's hosed this device... but I don't
have a clue as to what it could be.

Here's my system: Asus A7N8XE Deluxe (BIOS 1013) with AMD Athlon XP 3200+
and 1 gig RAM. ATI Radeon X800pro video card 1 Seagate 200gig SATA
hard-drive 1 Maxtor OneTouch II external hard-drive via firewire connection
1 Sony DRU 720A DVD-RW player

I have all the current nVidia motherboard drivers and ATI video drivers
installed. Everything else is working just fine.

Thanks.

I figured this one out finally! I noticed a USB driver called USBHS DFU
Adapter. I wasn't sure what it was so I did a web search for it. I located
an article that said that a update to this driver had hosed his flash card
reader. I rolled it back to the native Windows driver and guess what?
Everything works now.

The bad driver is: "USBHS DFU Adapter SCM Microsystems Inc. usb software
update released on February 18 2005". Not sure where this update came from,
but it's gone now.

You may have downloaded it from the MS Update site ?

Seriously, I did. After looking at my M$ download history in Windows Update
I spotted this item:

SCM Microsystems Inc - Other Hardware - USBHS DFU Adapter
SCM Microsystems Inc. usb software update released on February 18 2005.

So the moral is, if you have or plan to have a multi-card flash reader
installed on your computer, don't download this particular "upgrade".
(downgrade?)

The moral is broader than that. Don't get driver updates for any
hardware from the Windows Update site. Go to the hardware
manufacturer's site for this or to the OEM if it's a large OEM like
Dell, Gateway etc.

IMHO the "Auto Update" setting should not be the default (In fact I think it
should not be an option)
