Linux driver for usb-6341

[niiraka]

I noticed from the ni driver support page that there is no linux driver for daqmx usb-6341 or usb-6343. Is a driver possible comming in the near future?

Thanks

Unless NI is willing to disclose their ultra-military-secret specs, it's quite unlikely.

The USB subsystem enforces all consuming drivers to be GPL. (iow: fully disclosed),

which they just refuse.

This was a while ago, today is 9 years later.

Has Linux support for these cards "magically" appeared now?

This is the current status - https://www.ni.com/en-us/support/documentation/supplemental/18/daqmx-for-desktop-linux-tools.html

Thank you for the pointer!

Oddly enough, following the installation instructions to the letter still results in a non-functional system.

I am on Ubuntu 22.04.1, kernel 5.15.0-56.  The install completes, but then any data transfer fails with error -50152, which I think is the code for DMA not working!  The easiest way to see this is to run self-calibration via ni-hwcfg-utility.
