I am quite new at Linux and I have to install this SwissRanger camera on Ubuntu. I am trying to follow their USB mounting instructions and I got stuck.

From the instructions:

Modify the usbdevfs entry in /etc/fstab    
by setting devmode appropriately, for example:
usbdevfs  /proc/bus/usb  usbdevfs  devmode=0666,noauto 0 0

I am not sure how to obtain the usbdevfs program, and also after which, does it automatically mean that the camera will be automatically mounted everytime I plug in the USB?

Edit: There is no direct web-link, it is in a folder after running libmesasr-dev-1.0.14-706.i386.deb under the webpage http://www.mesa-imaging.ch/drivers.php

Can you give us a link to the instructions you're following? – rahmu Oct 17 '12 at 9:06

"usbdevfs" is not a program. The third line is the edit that must be made to the /etc/fstab file. What you can try is open up the /etc/fstab file using any text editor you are comfortable with. Note that you have to be root to edit that file. Then, just copy and paste the third line, i.e.

usbdevfs  /proc/bus/usb  usbdevfs  devmode=0666,noauto 0 0

at the end of the file. Save it, and restart your machine. Check if the camera gets mounted automatically.

add this to your fstab

/dev/sda1 /media/usb auto rw,user,noauto 0 0

then mount the camera by issuing

mount /dev/sda1

and have read/write access to it.

Depending on what version of Ubuntu you have, in the past I've plugged in the camera into the USB port and it instantly showed up on cheese.
