ethernet over usb gadget on Windows not working

Hi All,
I am running debian on my beaglebone black. I can’t connect to it using Windows XP or 7 over the USB ethernet gadget. However I can connect to it just fine on an Ubuntu machine.
So I think it is a problem with the Windows driver.
Windows sees the BBB and can mount it as a mass storage device, but no replies on a ping to 192.168.7.2
I installed the drivers from here:

Any ideas on what is wrong?
Thanks.
