Flashing Om2008.8 rootfs under Windows is *LONG*

[Andrew Chu]

Thanks for the feedback that the dfu-util for Win32 is that much slower 
on Vista.  I wasn't aware of that.  The changes I made to the dfu-util 
source code were minimal but they could use a code review (I've posted 
the diff below).  On Windows XP, I've never had to wait more than 20 
minutes to flash the rootfs so the issue might be related to Windows 
Vista, or LibUSB-Win32 on Vista, but unfortunately, I do not have 
Windows Vista so I cannot debug.  If anyone has the same issue on 
Windows XP, I would like to hear about it.
