Generating URB's ahead?

NTDEV
1

Hi All,

Is it possible to generate URB’s ahead and reply them lateron when the class
driver request for it??? I am trying to ask this because there is no way
that we can ask the class driver for more URB’s (controlling the
burstiness).

It would be great if some one can guide me.

Thanks,
-Kashi.

How many packets would you include? How large would they be? Which
pipe? How would you set the TransferBuffer?

Unless your driver has developed the ability to see into the future,
this is simply impossible.
