Re: Enable windows update for device driver search?

The tact i would take is to fix the configuration in Target Designer.

Try this -
From the desktop of the runtime that shows all the unknown devices, run
TAP.exe. That new PMQ will list the unknown devices, but it will also have
the vendev IDs for those devices!

Then try importing that PMQ into Component Designer and look at the
resulting device components that were detected. This will help you identify
true hardware components that your BIOS failed to report to TA.exe. Some or
all of these you probably want to manually add to your configuration in TD.

Note, i said 'true hardware'. If you're audio is hosed then this trick will
not work because you will still be missing some of the software enumerated
devices that form the audio stack. However, the good news is that there's a
tip article to help you identify them and add to your config (components
like 'Kernel Streaming User Mode Support', yes this is a software enumerated
device that PnP in the ENUM branch with the hardware):

Hello, I know that windows update does not work with XPe, but for some
reason there are a number of devices that are labelled as "unknown
device" in device manager. I was wondering if there is a way that when
i try to update the driver for the unknown devices, that it could
search windows update for a matching driver?

I ask this because apparently the devices.pmq file that i got from
ta.exe that ran on the target machine did not find everything (i
guess). Would it be any better to run tap.exe on a built image of XPe
running on the target machine, or is that redundant?

My main problem is I'm trying to get a touchscreen working/detected in
XPe, I have the drivers (no setup.exe), but nothing seems to work.

thanks in advance
