mandriva 2009: trying to use a raw USB device through VISA

[Achille_Taylor]

Hi,

I'm a real beginner at Unix, so please be patient 🙂

I have just installed Mandriva 2009 and LabVIEW 2009 on my laptop. My objective is to drive a USB raw device.

I went through some difficulties to install NI-VISA 4.5 and solved them by browsing in the forum. Some issues remain:

 - As I am not familiar with Unix, I am not sure to understand what "usbfs should be mounted with devmode=0666". Could someone tell me the rigth command line to enter?

 - When running AddUsbRawPermissions.sh, I am told that /etc/hotplug cannot be found. Reading the script, I saw that it is looking for /sbin/udevcontrol. I don't have it, I only have under /sbin the "udevadm" and "udevd" executables.

 - When running the VISA driver wizard, I only have access to PXI/PCI. Maybe it is related to former points.

 - When trying to launch the VISA Interactive Control, I get a nice bouncing cursor animation, but nothing else.

 - When trying to use the "VISA Find Resource" VI, Labview just crashes.

Thank you in advance for your answers.

Hello,

First, you should allow software to use USB devices by entering this command : 

mount -o devmode=0666 usbfs /proc/bus/usb

or this one :

mount -o remount,devmode=0666 usbfs /proc/bus/usb

And then tell me if you are still getting the same issues.

Hello,

First command line generated an error (translation from French: mount: you must specify the file system type). Second command line seemed to work. At least it didn't cause an error. Therefore I went ahead and tried the AddUsbRawPermissions.sh script, leading to the same error: -Cannot find "/etc/hotplug".-

Besides, VISA Driver Wizard and VISA Interactive Control still behave the same way.
