Hi,

I'm trying to help someone with their computer and though often fairly
knowlegeable about PCs and the way they work, I have been unable to repair
this particular problem.

The initial problem reported to me was that both printers that are connected
to the client (via USB) were no longer functioning.

I quickly discovered that in the device manager there were several yellow
exclamation points showing including that of USB controller. (As a side
issue, the video controller also had an exclamation point but the video
display was working fine!). Anyway, I went to support.microsoft.com and the
resulting page from a search suggested uninstalling the driver and
rebooting. It suggested that on reboot it would detect the "new" hardware
and install the drivers for it. It didn't. I tried manually to install
drivers from a windows subfolder called "last good" but still no driver
could be found.

Not too sure what to try now - and any ideas gratefuly received!

Thanks,

you probably need
to update the drivers
for those devices
that are connected
to the usb.

to do a little analysis,
simply disconnect
everything from the
computer except
the monitor, kb and
mouse.

then reboot and
see what the device
manager says.

if there are no yellow
marks, then you found
the problem,

which was something
you unplug and was
being uncooperative
with windows.

so replug what you
disconnected one
at a time.

each time observing
the device manager's
reaction.

If it was working before, you should start with a malicious software
scan. It can't hurt.

Download, install, update and do a full scan with these free malware
detection programs:

Malwarebytes (MBAM): http://malwarebytes.org/
SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

They can be uninstalled later if desired.

The best place for drivers for integrated devices - like sound, video
and USB ports is going to the the WWW site of the manufacturer.
Microsoft will have stuff for their software and only basic drivers,
but you need motherboard specific drivers to match the hardware.

You can click Start, Run, msinfo32 to get general information about
your motherboard and BIOS, then visit the Support, Downlaod, Drivers
section of their site to see what they have. You may have to get a
set or "pack" of drivers or they may be separate - like just the USB
drivers.

You need to get the !s to go away for the afflicted devices.

Download the and right click you afflicted devices, right cick, Update
driver and point it to the new downloaded stuff and let it find/
install the new driver. You can note the current driver information
while you're there.

I would practice on the USB since the video is "working". If you
tamper with the video first, it may stop working, so save it for
later.
 
Hi db,

It's the USB controller that's showing the exclamation points not the
devices themselves. Rebooting does nothing (printers attached to a USB port
or not) Thanks for your response. This problem still exists. Any other
ideas?

Thanks,

Jim
 
yeah,

if they are external hubs try
unplugging them and re
plugging them back into
the pc and ensure they have
an external power source.

also, try uninstalling the
driver for the controllers via
the device manager.

also, double check your
bios to ensure any settings
to the usb are enabled

and check your computers
home site for updates to
your bios or drivers.

if the above doesn't help,
I'm basically out of idea 'errs.

Hey Ben,

Thanks for taking the trouble to respond. Unfortunately I had already tried
all of the things you have suggested.

I think I'll advise them to get a new PC!
