a different USB question

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.

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 should have mentioned that I deleted the INFCACHE file based on your
responses to other people.

Does Vista have a Wizard that is supposed to take over when you connect a
new USB device?

Galen,

I've not seen a wizard for use in installing USB devices. Installing USB
devices is supposed to be no different than installing other devices, and for
those devices that are natively supported by windows, substantially
automatic, as far as I know.

However, there is more to this than just the operating system, as indicated
in my earlier comments. The operating system needs the cooperation of the
rest of the components included in a computer, including the USB device
itself; it must comply with the USB standards. Sometimes devices don't
comply sufficiently, but who knows what the issue is in your situation.

One thing you can do to try to resolve this problem, is to conduct more
involved troubleshooting. HP established the following site to assist its
customers in resolving just the kind of problem you are having. Since USB is
a universal standard, the steps involved at the site can apply to anyone.
Take a look, if you're so inclined, to see whether you can identify something
to resolve your problem, here:

I've directed others to this site, and some have responded that they found a
solution. Let us know whether you find something.
 
Well that was interesting. There was nothing in the article, per se, that
covered my situation. But I got to thinking about it and uninstalled the
Jungo driver.

I rebooted with USB device turned on. Sure enough it wanted to find the
driver. I pointed to Windows\Inf and it installed the app's driver.

Of course running the app gave a USB not found message. So now I ran the
Jungo install to put in the kernel drivers and the app worked.

So Vista wants the app driver first. Then the kernel driver. Thinking back
to the Business edition I had completely removed a Jungo driver that was not
compatible but I never removed the old app inf file. It was the old app
driver that was used because it was there before I installed the Jungo
kernel drivers.

So my Vista install has to be reversed from the Win98 and XP installs. First
put the app driver in Windows\Inf and then turn on the USB device. Running
the app will fail at this point. Now install the kernel driver.

I will make a clean install of Vista on another test computer to verify
this. Thank heavens for the MSDN subscription.

Galen,

Any landing you can walk away from is a good landing. Yes, indeed, that was
interesting. You never know. One poster couldn't get her Vista to recognize
a USB hub. Another poster couldn't get her Vista based computer to recognize
her USB external hard driver until she connected it to a USB hub. Go figure.
