Yes, I know it :). But I use "complete" function in usb-driver.
And I don't think, that it's correct to use args "urb" in this function
from user-space.
As I know this structure is stored in kernel-space and I can't modify it
from application.
I talk about interface between driver and application or library.
After getting interrupt from device and making some operations for that
I need send some data to application. For that I have to notify an
application
about it. I think IPC, like semaphores, is one of the way, but may be
there are other
ways for it?
With many thanks.
