I think you are out of luck. The only way to keep the existing non-WinUSB driver is to use libusb-win32 filter driver and the 0K branch of libusb-pbatard. However, it is not expected to work if you use libusb-win32 filter driver (upper filter driver) on top of UMDF driver as per Microsoft document. http://msdn.microsoft.com/en-us/library/windows/hardware/ff540215(v=vs.85).aspx WinUSB/UMDF do not support the installation of kernel-mode drivers, such as filter drivers, as an overlying layer on the USB stack. In reality, it is more complicated than the above. http://msdn.microsoft.com/en-us/library/windows/hardware/ff561214(v=vs.85).aspx I think libusb-win32 filter driver does not fulfill the condition to make it work with UMDF drivers. But you can still try it to confirm whether it is true or not. I have used libusb-win32 filter driver on top of WinUSB and it seems to work. But we have reports libusb-win32 filter does not work on top of UMDF. http://sourceforge.net/p/libusb-win32/bugs/73/ -- Xiaofan ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
