Hello,
I have a cRIO 9067 and would like to interface to an instrument that has a SiLabs USB-RS232 converter. I can comminicate with this instrument easily on a Windows PC. I am able to see the device in MAX when its connection the cRIO. IT shows up under "Devices and Interfaces" as "USB0::0x1FB9::0x0100::121A00A::RAW" with the Model number and the device description.
I've followed the description at this link, but I don't get a ttyUSB# devices.

Is there any chance to get this working on the cRIO as a serial port?
Thanks.

I don't have that file /etc/mdev.conf.
Is it possibly in a different location on the 9067?

I created the file at /etc/mdev.conf with the line:
ttyUSB[0-9]* root:tty 666
restarted the cRIO, but the device still shows up as a usb raw device.

Hello immercd1,
Lots of changes were made in the file structure when the 9067 was released. This document helps outline how to connect to USB devices with the new structure:
Let me know if you have any other questions!

After some digging, talking with NI Folks, google, and Talking with Folks at lakeshore.com (device vendor) here's what I've piece together on how to get this to work:
#typical devices
ttyUSB[0-9]* root:tty 666
KERNEL=="ttyUSB[0-9]*", OWNER="admin", MODE="0666"
