We plan to use endpoint 0 (control type) for some function specific
WRITE
functionality (like beep buzzer, blink error LED)

Is it possible for the functional driver to directly access usb
endpoint 0?
I could not find any DDK calls that can allow this access.

Thanks
 
yes. you can send a control transfer (_URB_CONTROL_TRANSFER(_EX)) down the
stack.
