> So what you say are that reading works for OHCI , EHCI, UHCI and writing
works if you don't exeeds max size?
Hmmm.. I would say: it _may_ work. You just receive only max packet size
data amount from endpoint per frame in this case. ;-)
> Writing to isochronous are only used for things like sound output (or
are it the mic) and writing to disk(if isochronous can be used for disks)
isochronous transfers are targeted for time-critical data stream
applications. There are no guarantee that all frames you have send will be
consumed by endpoint.
