SFP-PLUS-I2C
------------
============
Running on Ubuntu
=================
To run SaFariPark on Ubuntu two things need to happen:
1) The rights of the FTDI device must be relaxed such that any use has read and write permissions
2) the ftdi_sio driver must be prevented from loading, as it will interfere with opening the device
Relaxing driver rights
----------------------
Create a file named 90-ftdi in /etc/udev/rules.d/ and put in the following statement:
SUBSYSTEM=="usb", ATTRS{idVendor}=="0403", MODE="0666"
Prevent loading of the ftdi_sio driver
--------------------------------------
Edit the file /etc/modprobe.d/blacklist.conf and append the following line:
blacklist ftdi_sio
Note: This will prevent any FTDI based device from being loaded as a USB serial converted.
