Hi,

I think the beginning of the transaction is that 8 byte
setup TD, which already reset to DATA0. The (optional) follow
up data TD start at the second TD, (if any). Since they are pointed
by the same ED, I guess the data TD should be able to using toggle
bit, which was reseted by the first setup TD?
With all the different versions of OHCI silicon around, this is
a case where I'd say "better safe than sorry".  That may just
be paranoia, but on the other hand we _know_ all the current
"works with Linux" silicon works with DATA1 there today, and
there's no need to change it.


Should I force to reset the first data TD (which is the second TD in
the whole transaction) to use DATA1 then do toggle for the rest of
data TD?
That's how I'd do it -- so your update is only to support more
data stage TDs, not in how the first (and usually only) one of
them gets initialized.
