USB interrupt

Hi to all,

is it possible to perform an interrupt on USB pheripheral by reading (PC side)?

In other words, I'm creating a firmware that use USB with a single EndPoint in reading (STR7 -> PC), then I modified usb_conf.h with below command line:

#define EP1_Callback EP1_isr //EP1_isr Interrupt Endpoint Routine

By PC side, nevertheless, when I perform a reading, the interrupt does not generated then EP1_isr does not executed!!!

I hope that is a my error, could you help me to found it or suggest another solution?

Thanks in advance to all

null#define EP1_Callback EP1_isr
