Hi Gadiyar,

I can not find the description of your understanding David
has expressed about the patch, so I think we need David to
give a explicit viewpoint.
In fact, this patch doesn't modify g_zero almost(see patch header),
and only introduce a standalone configuration in g_zero to
do ISO tests, and doesn't modify any use cases of current g_zero
for bulk or control transfer test.
Also, if we implement the ISO test in a new gadget driver, which
vendor ID and product ID can be used for such purpose?

This patch can meet the requirement already.
thanks,
