Compare your code with this example.

\firmware\slave\sl811s.c gives a slave HID example for SL811 on an EZ-USB chip (8051 core).


To debug the USB enumeration, a hardware bus analyzer is a must.
If you don't have it, download and 'evaluate' this software sniffer.
Although software sniffer cannot fully replace the function of hardware analyzer, it's better than nothing.
