usb 6218 on ubuntu 7.10

Should lsmod show me a list of installed nidaqmx base modules?  When I call lsmod, none of the installed modules appear to relate to National Instruments.

Let me explain a little bit about how the 621x devices work, but after that, you'll need to do the digging and poking to figure out how Ubuntu configures itself and its USB devices, or ask the community for help as you learn about udev and kernel events.

The USB-621x devices are designed such that they require firmware to be downloaded to them by their host every time they are plugged into the system. When they first connect, they appear as a device in firmware-loader mode (with PID 7269). Once their firmware is loaded, they have a distinct personality and reappear with a different PID. The PID for the 6218 is 7272. All of this is discoverable from the udev *.rules files and accompanying scripts.

Now for the explanation of lsmod. NI uses private methods for interacting with its USB devices, and since the authors for the USB Linux kernel modules have requested that other kernel modules that call into their modules be GPL licensed, NI cannot protect its secrets and also satisfy the USB kernel module developers. Instead, NI communicates to USB devices through the public user-space USB interface provided by the kernel. That explains why you don't see any NI modules attached to your USB DAQ hardware: NI can't run at the kernel level, so it wrote the driver in user-space.

Any success? Im having the same exact problem.

well, it looks like /etc/udev/agents.d/ doesnt even exist. (etc/udev does exist). Which rpm package was supposed to install this?

Sadly, I never managed to fix it.  I am currently using my NiDAQ card in Windows and communicating with the linux computer/robot over the ethernet.  It is not a great solution, but it was the only thing I could manage.  If you manage to make it work, please update!

I tried on OpenSUSE 11.1 (not officially supported by DAQmx Base 3.3). It did not work after this installation because hotplug and pam_console do not exist anymore.

I added the foolowing rules in /etc/udev/rules.d/50-nivisa_usbraw.rules

ACTION=="add", BUS=="usb", SYSFS{idProduct}=="7269", SYSFS{idVendor}=="3923", RUN+="/usr/local/natinst/nidaqmxbase/bin/niusb9162dlfw"
ACTION=="add", BUS=="usb", SYSFS{idProduct}=="7272", SYSFS{idVendor}=="3923", MODE:="0666"

Now, the green light on my 6218 device is blinking and lsdaq finds the device in user mode.

Recently, many distributions switched udevcontrol for udevadm and broke our scripts. For a more complete explanation and work-around, see my post in the Linux Users Group: http://decibel.ni.com/content/message/17590#17590 .
