I see in the other email you have solved the problem
with a brutal force problem.

>From the above description you have an older version of
libusb-win32 version installed and the libusb0.sys was
acting as a class filter driver for all USB class it can
attached to.

What you can do is to uninstall it first and then
reinstall the new version of libusb-win32.

If the above does not solve the problem, you can use
the command line install-filter to remove all class filter.
       install-filter uninstall --all-classes

http://libusb-win32.svn.sourceforge.net/viewvc/libusb-win32/trunk/libusb/src/install-filter-help.txt?revision=413&view=markup

After cleaning up the old thing, then you can use
the new GUI Inf-wizard to install the device or
GUI Filter driver to attach libusb0.sys filter
to your specific device.

More info on the filter driver.
