These changes solved my Windows hanging problem as well.  

I do not think the last change (USB_CDC_CIF_NUM) is correct though.  Changing this line caused my Linux PC to no longer connect to the Overo attached to the Robovero.  Keeping this line as-is kept Windows and Linux working correctly.

Thanks for figuring this out!

I've tested your changes on both Windows 7 and XP with the default INF file
and they work. You need to change to tell it to connect to a
COM port rather than a ttyACM port to run Python code. That last line with
USB_CDC_CIF_NUM, does break compatibility with Macs though.
