Hi,all Now,i have developed dm320 gadget driver. 1.I look through some udc's corresponding functions at kernel source.And i find there will implement IN/OUT through readfifo(writefifo) or DMA . Some days ago,Alan told me "file_storage.c will call usb_eq_queue(),which calls your dm320_gadget's ep->ops->queue() routine",that means file_storage will implement IN/OUT through readfifo(writefifo) or DMA Is it right? If then,How about my rx/tx interrupt?They also will call the same functions. So i am puzzled,If there is a IN from storage,which one will be invoked? dm320_eq_quene or my rx interrupt(which comes from usb core interrpt)? 2.Maybe i am a newbie for usb,i even don't know what kinds of things i need to do in my dm320_eq_quene function, And what it mainly do?Can u tell me?
