It still may not work for the reasons I outlined - namely, that interface doesn't know a write transfer from a test unit ready or a hole in the wall, and so can't intelligently split up a transfer since it doesn't know things like where the number of bytes go etc. The same restriction applies to any "pass through" interface I know of that "sane" is using. I just saw the message about the "kvasize" structure member. I'm pretty sure that didn't exist in the old days - tomorrow I'll look and see what it does.
