wine users - Jul 2008 - Plug & Play registry update for USB device?

Hullo.

I'm running Darwine 1.0 on a MB-Pro with OSX 10.5.1..

We have an in-house developed Windows test tool.  It runs OK, except... 

One of the (important) things it does is query the windows registry for all
USB-connected devices with a particular GUID under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\blahblahblah...

The guy who wrote the tool tells me that he queries for devices with this GUID. 
Then he populates a tree and lets the user choose a device to interact with from
this tree.  The interaction bypasses any drivers and talks directly to the (USB)
device.

When I run the tool, it pops up the device selection dialog, but reports that
there are no devices available, even though one is plugged in (and the Mac
driver can see it!).

I'm guessing the problem is that Wine is not updating the registry when the
device is plugged in (i.e. plug&play not supported??).  Any clue what might
be going on here?  I ran several google & forum searches, and while I found
plenty on how to get drivers to work (or not), I didn't see anything like
this...

Hi,

        Maybe you can try making the USB device being seen as a serial 
device !?!? 
        Take a look at this message:

Naah.  Won't work, for a couple of reasons.  First, it would mean using the
serial driver to talk to the device... and the device isn't a serial port. 
Second, it would mean changing the tool... and I don't have access to the
tool to change it.

I really need to have the registry updated with the proper entry for the device
when the device is attached.  I have a feeling this will mean
"manually" updating the registry when I plug in the device, then
running the tool... since the tool is depending on the Windows P&P logic to
have added the device to the registry...
