Hi Friends!
I am newbie to Vusb. i downloaded VUSB and tried several example like hid-mouse,hid-data with attiny85 MCU.It worked with MINGW host.
Now i am trying custom class, and hid-custom-rq examples,but i am facing error when i MAKE in MINGW using 'make -f makefile.windows'

[BELOW I have copied statements from MINGW client.]

E:\vusb-20121206\vusb-20121206\examples\custom-class\commandline>make -f makefil
