Cannot see my instrument in NI-VISA config, Red Hat 5, USB connection.. HELP

[DavidLoganProgrammer]

Hey everyone,

Trying to automate the keysight E5071c network analyzer, however, NIVISA configuration utility doesn't find the device

My setup:

Red Hat 5

NI-VISA 5.4.4 installed withtout any issues

keysight E5071C,  connected via usb.

so far i've tried almost everything, at least as far as i know.

I found the usb device location for my instrument at          /dev/usb/usb488-0957-0d49-0-MY46522561.

-I ran the hotplug fix and supplied the vender and product ID, said it worked successfully

-I ran the NI-VISA configuration from the /vxipnp/linux/NIvisa/USB, and it doesn't show any USB devices.Only serial.

-running lsusb -v produces

-I've also granted r/w permissions to all users on all usb devices.

-i've added....:                  none         /proc/bus/usb        usbfs          devmode=0666       0  0

  to the /etc/fstab file, and rebooted.

-and lastly, according to an NI troubleshooting guide, I added   'blacklist usbtmc'   to the /etc/modprobe.d/blacklist   file

Any more suggestions?

Thanks for your time!

Hi DavidLoganProgrammer,

Are you using a real-time target? If the USB device is a CDC ACM class device, the NI Linux Real-Time OS already has a driver for that device which is preventing NI-VISA from claiming the device.

Here are few resources that might be worth looking into.

What is a NI Linux Real-Time OS? I do not believe we installed anything from NI prior to the NI-Visa 5.4.4 libraries

[DavidLoganProgrammer]

/sbin/rmmod cdc-acm
ERROR: Module cdc_acm does not exist in /proc/modules

I don't believe that i have a ni linux real time os

The USBTMC driver is blocking VISA ? See this document.

giorgiana,

Don't hijack an unrelated thread. Please start a new one with additional details.

Hi Mkossman,

I went through those steps, but to no avail. 😞

[mkossmann]

There is one thing, what I think is missing the document: You could verify, that the blacklisting of the USBTMC module really works by running "lsmod". If the module  isn't listed anymore there is still a little chance that the driver is compiled  hard into the kernel.  So checking the kernel configuration could make sense,too.    If the USBTMC driver is neither loaded as module nor build into the kernel  I have no idea anymore.          

[DavidLoganProgrammer]

I run lsmod and usbtmc is at the top of the list. So it's there.

My /etc/modprobe.d/blacklist file also has 'blacklist usbtmc' at the top of the file

What should i do now?

thanks
