I tried compiling your source code which resulted to a HEX file.
then I tried comparing Your Hex file to My Hex file....and found that there is difference of 10Kb.
using your HEX file, the windows can recognize the primer.
but using my HEX file, it comes out as "UNKNOWN"
by default I just loaded your project file and start "build"
I'm just wondering why is there a big difference in the HEX file size between yours and mine?
do you have any other special setting?
pls advise.
thanks.
