USB 6210 times out with 200284 on RHEL5 using nidaqmxbase 3.6 while trying to sample continuously.

John,

That's exactly what I'm doing in my workaround as well.  I sample really slowly in comparison (testing of HVAC equipment) but still far faster than I need to.  When the DAQ crashes, I shut down and then restart the task, resuming where I left off.  I'm also running the TDMS logger manually in code, so it doesn't cause any hiccups in the file; just causes a block of data to go missing.

I think the OP needs every last drop of data, though, and that wouldn't be an acceptable workaround for him.

Glad to hear you've got it to work acceptably as well.

Hi all,

I'm glad that resetting the device is an acceptable work around for you guys.  I'm still working with R&D to get more information and will continue to monitor this thread if you have any further questions.

Calmor, as to your question about what speed is acceptable, I don't know the answer right now; I'll let you know when I have more information.  Again, please feel free to post here if you have any further questions.

Thanks,

Hi All,

Sorry I haven't been checking this forum lately. I'm disappointed to hear that the USB devices aren't going work at full speed on Linux.

I've got a fixed setup that uses PCI cards and they work great, but the USB devices are for a portable setup with a laptop, so I won't be able to switch to PCI cards for that. The workaround discussed in previous posts won't work for me. I can't afford to miss scans and resetting takes about 1 to 2 seconds, which is much too long. The Linux platform allows us to use a bunch of freeware and scripting capabilities that make it an attractive and inexpensive platform, so switching to Windows isn't very viable either.

I'll have to discuss this with the engineers whose project this is and see where we can go from here.

Thanks again for your help,

-Tom
