Galen,

It's hard to say what the problem is. Not all computers are the same. That
is, they may have different motherboards, chipsets, chipset drivers and
BIOSs, all of which can impact on the way USB reacts. There are other
variables as well.

One thing you can try is to delete the INFCACHE.1 file, which can get
corrupted with bad data and cause issues with identifying drivers. The file
is located at C:\Windows\inf. There, scroll down to the INFCACHE.1 file and
right click it and select delete. To do this, you will likely have to give
yourself permission to delete it, because of Windows built-in security you
know. Just right click the file, select Properties and then click on the
security tab. Under that tab you can give yourself permission, because you
are the Administrator. It does no harm to delete the file, even when it has
nothing to do with the problem. This step sometimes works, but sometimes
not. Let us know what happens.

Vista Home should be able to recognize your USB device if other versions of
Vista can do it, but this assumes that other variables don't cause a problem.

I use the Jungo WinDriver to create an install for my proprietary USB
device.

This install goes beyond the usual USB driver in that it imbeds itself into
the kernel and creates a new entry in Device Manager. This new entry is not
under the USB headings.

In addition a driver for my app is created as an inf file and is placed in
Windows\Inf.

This same install has been used on a Vista Business edition and works fine.

When installing on a Vista Home edition, the Jungo driver is installed and
the Device Manager entry appears. However when the USB device is first
turned on (connected to a USB port), nothing happens. The connect sound is
heard and that's it.

Normally on Win98, WinXP and Vista Business, the first connection of the
device causes a search for device drivers. And, of course, it's found in
Windows\Inf. This places an item under the Jungo heading in Device Manager.

Is Vista Home just to dense to figure it out?

All of the above is done as an Administrator.
