Re: [Libusb-win32-devel] Driver installation failed, Error 39, Vista 64 bit

Also, please have try to obtain the C:\Windows\inf\setupapi.dev.log from 
the customer's machine, at it may offer some insight as to why Windows 
cannot start the driver.

Each of the driver installation steps are logged there, so if the 
problem was with the installation, you should see a detailed error there.
