i am so lucky to find this thread for my NIarc 2014 project
hi all
i can manage to see lidar in NI max as same as this thread showed.
but i can see the them in the example vi (like Hokuyo URG Series Configure and Acquire Data)
only ASRL1 AND 2 available after refresh
please give a hint on it

Hi Jeff,
If you right click on the drop down box and select Choose Device Class, you should be able to make sure the LiDAR isn't filtered out of the selection.
Kind Regards,

hi alex
trying test lidar on myrio usb port with "hokuyo urg series configure and acquire data.vi"
it does work, but took too long to refresh a new frame.
only the first time took 2 second, then took longer and longer at each time lauchthe vi, and getting stable untill 1frame/minute
should somewhere to set the refresh rate?

Solution for the device-recognition (USB):
Update VISA, open NIMAX, browse to the myRIO, click on software, click on "add or remove software" (I don't know the exact description in english 😕 ) (the button is locatet at the upper part).
Look for the checkbox named something like USB-drivers and CHECK IT. Click on save and restart the myRIO...
It should work

Hi Alex,
I am trying to reproduce the same steps ( I must say that I am quite new in LinuxRT and myRIO ) and I cannot find the mdev.conf int the "etc" directory - is there something else that I should do, or maybe I have missinstalled something ? I have used both PuTTY and FileZilla to search for it, but without luck.
I have also attached a printrscreen with the directory listing on myRIO.
Thank you in advance,
Denis

Hey, you may want to look at this (copied from another post)
16. Oct 28, 2014 5:20 AM (in response to FCGoat) Re: Problems with NI-VISA and USB Drivers on cRIO 9068
For the newer NI Linux RT 2014 platform the mdev rule to assign permissions won't work anymore. Instead it uses udev. For this to work you need to add a file "/etc/udev/rules.d/ttyUSB.rules" with following contents:
KERNEL==”ttyUSB[0-9]*”, GROUP=”tty”, MODE=”666”
I got with this addition a Silicon Labs cp210x device working on a cRIO-9066.

Btw, I used this successfully to control a Phase Matrix QuickSyn Synthesizer (its actually owned by NI).
It first showed up as ttyACM0 "not present"
Following the instructions at the beginning of this topic and creating the file in my previous post using ttyACM.rules as filename fixed the problem and I am now able to control the quicksyn without a problem.

Hi CptRon,
Thanks for your reply - it helped to save a lot of time ( I kept looking for that file 🙂 ).
What we are trying to achieve, is to control an GW-USB-05 on myRIO
( http://www.iqrf.org/weben/index.php?sekce=products&id=gw-usb-05&ot=gateways&ot2=gw-usb-05 )
Hope that it will work - anyway, I will let you know about the result.
Regards
