So, don't use the ISO, duh. ISO is an inherently lossy, contrieved access method, not well suitable for anything.

There's no reason whatsoever to design a new device firmware with ISO endpoints. > - I am using a quite recent linux kernel (2.6.18, coming with with OpenSuse > 10.2) Har har har. Naive. Talk to Christopher Mongomery and Alan Stern about the issues in detail if you're interested. -- Pete ------------------------------------------------------------------------- Take Surveys.
