Signalyzer H series Drivers Installation Guide for Linux

This tutorial uses the Ubuntu 8.04 (Hardy Heron) distribution of Linux. As Linux distributions vary these instructions are a guide to installation and use and may require some investigation on other distributions.

Following tutorial assumes version 0.4.15 of libftd2xx is being used.

Installation

Unzip and untar the file given to a suitable directory

gunzip libftd2xx0.4.15.tar.gz

tar -xvf libftd2xx0.4.15.tar

As root user copy the following files to /usr/local/lib

sudo cp libftd2xx.so.0.4.15 /usr/local/lib

Change directory to /usr/local/lib

cd /usr/local/lib

Make symbolic links to these files using the following commands:

sudo ln -s libftd2xx.so.0.4.15 libftd2xx.so

sudo ln -s libftd2xx.so.0.4.15 libftd2xx.so.0

Change directory to /usr/lib

cd /usr/lib

Make symbolic links to these files using the following commands:

sudo ln -s /usr/local/lib/libftd2xx.so.0.4.15 libftd2xx.so

sudo ln -s /usr/local/lib/libftd2xx.so.0.4.15 libftd2xx.so.0

Activate usbfs for current session by issuing following command:

sudo mount --t usbfs usbfs /proc/bus/usb

To ensure the usbfs is enabled and active for subsequent log ins, edit /etc/init.d/mountdevsubfs.sh:

sudo gedit /etc/init.d/mountdevsubfs.sh

Scroll down to line 39 and find following lines:

# Magic to make /proc/bus/usb work

#

#mkdir -p /dev/bus/usb/.usbfs

#domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644

#ln -s .usbfs/devices /dev/bus/usb/devices

#mount --rbind /dev/bus/usb /proc/bus/usb

Uncomment (remove #) 4 lines of code:

# Magic to make /proc/bus/usb work

#

mkdir -p /dev/bus/usb/.usbfs

domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644

ln -s .usbfs/devices /dev/bus/usb/devices

mount --rbind /dev/bus/usb /proc/bus/usb

Save the file and exit the editor.

Reboot

To enable usbfs on other distributions following line may need to be added to /etc/fstab:

none /proc/bus/usb usbfs defaults,mode=0666 0 0 (use usbfs in 2.6 kernels)

and remount all in the fstab file

mount -a
