What is the current take on the max Isoc throughput
NEC EHCI's eg those found on the Adaptec high speed USB 2.0
4 port card? The chio is the D720101GJ.

Nobody's been using high speed ISO much on Linux, and so the periodic transfer support hasn't ever gotten much use or development. Which means that people haven't really been noticing how much of the ISO throughput is available through any chip.

There was a patch against 2.6.0-test7 from Michal Sojka
that may be of interest, if you want to try it.  Such
changes couldn't possibly be merged until 2.6.1 at the
earliest though.
