Dear all, I am recycling an urb: first I fill it with FILL_BULK_URB,
then I send it. Once it completes, I use FILL_BULK_URB again
with EXACTLY the same parameters before sending it off again.
Can I eliminate the second FILL_BULK_URB? In other words,
does the USB subsystem modify any of the parameters touched
by FILL_BULK_URB?
Thanks, Duncan.
PS: For reference
#define FILL_BULK_URB(URB,DEV,PIPE,TRANSFER_BUFFER,BUFFER_LENGTH,COMPLETE,CONTEXT) \
do {\
spin_lock_init(&(URB)->lock);\
(URB)->dev=DEV;\
(URB)->pipe=PIPE;\
(URB)->transfer_buffer=TRANSFER_BUFFER;\
(URB)->transfer_buffer_length=BUFFER_LENGTH;\
(URB)->complete=COMPLETE;\
(URB)->context=CONTEXT;\
} while (0)
