I have a USB DAQ device which I have used in Windows a fair bit (tinkering). Now, I'd like to get serious with it using my Linux system (Ubuntu 10.04). I see that there are some drivers listed on the Measurement Computing site for Linux, but I have no idea how to go about 'installing' these. Also, I see references when I search online for using this kind of device with MATLAB, which I do not have. I am hopeful that I can use it in C/C++ somehow--for instance with QT Designer. Has anyone had experience using a DAQ in Linux? Any guidance? Thanks! http://www.mccdaq.com/usb-data-acquisition/USB-1208LS.aspx

Low-cost National Instruments USB data acquisition (DAQ) devices provide basic functionality for applications such as simple data logging, portable measurements, and academic lab experiments. They are affordable enough for student use yet powerful enough for more sophisticated measurement applications. Now the query is how to use this kind of HW under Linux and ur distro is ubuntu….
U may download KNOPPIX CD with comedi and use it for working on the distro.
The Data acquisition softwares are: qtscope, qtwave, comedirecord, xoscope. u may use them either way. The usb daq is part of the comedi project,
for more info link here: www.comedi.org/
It is better to use “Ubuntu Lucid Lynx” which comes with all drivers, firmware and an up-to-date comedilib package.
OR use Ubuntu Karmic Koala which also comes with all drivers and an up-to-date comedilib package. Just need to install the firmware files (\lib\firmware)
First download firmware files, change to the root directory: cd / and unpack the files: tar xzvf /tmp/usbdux_firmware.tar.gz and then install.
Remember it varies from kernel version such as 2.4 and 2.6 !

    Sorry, I am just a beginner, but I do not see USB-1208 in the list of supported hardware on COMEDI project webpage: http://www.comedi.org/hardware.html

     Will it work for it? What driver should I download ?
