Sorry that I can't help, but rest assured that there is at
least one other (me) with the same type of issue.

I have a similar problem. My printer and PDA update work
fine, but my card reader and scanner are no longer
accepted.
Help please.

Did you try uninstalling the USB controllers and hubs in safe mode (press
F8 during after the POST completes and before Windows begins startup)?
Then reboot into regular mode and let Windows re-detect all the USB devices
and such.

Dear Dave,

tried uninstalling in safe mode as well, the strange thing is that the
usb wireless receiver, the printer, the webcam all work, but the
memory reader and the scanner got the malfunction message still.....

really running out of options.....

david

dear all,

few things I have tried to no effect.

1) I have noticed that all my usb 1.1 devices are ok, but not the 2.0
devices, even though they all work before.

2) I have uninstalled all the root hub and controllers in safe mode -
windows came back and found all the hubs and controllers, including
all the 1.1 devices, but when I plug in the 2.0 devices, both of them
(scanner and memory card reader) show up as unknown device

3) I have updated all the latest bios and drivers - no help

4) tried to applied some of the usb related patches I can find in the
microsoft support site - no help

Beginning to wonder if there is a specific windows usb 2 driver that
is corrupted, and it's preventing windows to reinstall the right
driver, if anyone can point me to the right file, that would be great.

thanks.

david

Posted this previously concerning USB2.0.not sure any one read it.. SP1 in
place?...Do NOT download any other drivers etc for this from any other site.
Most importantly; check your hardware configuration to see if you have an
'enhanced' USB controller listed in there, if not, you can try re-installing
your PCI card and see if that does it. the key word is 'enhanced', if it
isn't there, you don't have USB2.0 working..

dear all,

some new info to share, and may be this is a little closer in solving
the problem.

recap: my usb2.0 devices are showing up as unknown deviced in device
manager, have tried everything including deleting root hub and host
controller.... windows came back and recognised everything except for
the 2.0 devices (which include a usb memory reader, and a scanner)

have also applied the latest patches of everything....... and most
importantly, all these things at one point worked on this system, and
I think it's after some windows update that this thing start failing.

new info:

This is where it gets interesting. If I delete just the usb host
controller (sis enhance controller) then the system will immediately
recongised the usb memory reader and the scanner, but will of course
tells me that I am plugging usb 2 devices into usb 1.0 ports. What
this tells me is that the hw and the devices are all working, and
there is something wrong with the software configuration....

I have tried to apply a good version of the usbehci.sys driver, tried
to clean up all existing usbehci.sys files except for the one in
systmer32/drivers directory. I have updated that file to the latest
from microsoft, which is version 1243. none of these helped. As soon
as I re-enable the enhanced usb host controller in device manager, the
usb member reader and scanner will become unknown device again.

so close.... and still so frustrating. Well, at least I can do a
temporary get around when I need to.....

any thought to this?

david

You may have tried this but it worked for me in a similar situation. I
unplugged all of the USB devices. Then I deleted the devices and hub from
the device manager. Then I rebooted letting it find the hub again. Then
I plugged in each USB device one at a time and it discovered them fine.
