i've many problems with mcf51jm128 and cmx usb stack, in host mode. The problem is in the handshaking phase of this kind of requests:


direction: OUT (host to device)

type: control transfers

length: greater then zero


the device doesn't send the zero length packet...i tried different types of device, also using the example project for HID keyboard class...the only instruction that use this kind of transaction is:


hid_kbd_set_leds(/*data for leds*/);


if call this, nothing happens...


can anyone help me? i can't find the errata of the cmx application note...

thanks a lot!! excuse disturbing
