I have tried just about every permutation of paths through this device
driver update process. In the scenario you describe, I am presented an
error "The folder you specified doesn't contain a compatible software
driver for your device. If the folder contains a driver, make sure it
is designed to work with Windows for x64-based systems.

In yet another scenario (hard to duplicate), the libusb-win32 category
of devices does appear in the device manager and indeed the device as
does appear. But the testlibusb program, as well as our own software
doesn't see any device.  As I stated, the only way I've been able to
communicate with my device on Win 7 is use the "Install Now..." button
in the inf-wizard.exe program. When I do that, testlibusb and my own
software can communicate with the device just fine.
