Dear All
I designed my own HW with STM32F103VBT6 MCU and at first step,testing two blinky/(RTX) examples that was fine (little problems solved in programming).
Recently I tried the USB HID Device programming, Step by step as example in Keil MDK5_getting_Started manual. but unfortunately it was failed,(when connecting to PC nothing happened and no device detected).
As I don't have any USB experience,(but reading documents about USB), I can't recognize the problems. I am sure about my HW which i test it cold frequently.
does anyone knows the point I missed the right way?
best regards.
