I'm wondering what sort of DAQ hardware people are generally using? I have various AnalogIO and DigitalIO needs, and bought a National Instruments USB-6211 DAQ. It turns out that NI doesn't support their USB cards on Linux, nor support any cards on Ubuntu. (worst case I may be able to run a separate Windows machine with a ROS node to do the DAQ stuff).
Since analog and digital input/output are common among roboticists, is there a DAQ card that works well on ROS and Ubuntu? Thanks.

In particular, I need to do some fairly fast analog output, on the order of a couple hundred kS/sec, on two channels. None of the NCD devices seem to be very fast, and none of the Arduino solutions are very fast either. I could use an AVR with a DAC, but I'd like an off-the-shelf solution.
