Hi Michael,
(it's top secret but... :-) I'm just preparing an A/D USB 2.0 card with
max 1MHz/12bit continous sampling rate and 30MHz burst sampling/trigger
and 16 inputs. It has just passed CE marking. If you want to test the
driver with me you can get the card in about a month. I'll merge the new
driver into comedi CVS as soon as Frank has released a new version of
comedi. Don't want to screw this up now.
BTW: the usbdux also runs under 2.0 but it does only 8kHz sampling...
/Bernd
