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?
