I have nothing against using iso mode (especially after I included it in
the patch I'm trying to push :). But I suspect that misbehavior in bulk
mode and iso mode may be due to a common cause, and this cause should
better be narrowed down.

May well be, but since we're about to put a device-specific workaround
into the generic core, we'd better know for certain. E.g. if this turns
out to be a hcd problem like the one Duncan mentioned, we're better off
making this a case for hcd maintainers. If the modem can be proven to
be non-conforming, we can make it a case for ADI so that they put a
workaround into firmware if possible (I understand they are cooperating,

If you have access to windows installation, you can try using USB
sniffer by Benoît Papillault:
It proved very useful to me when I coded cxacru.
