MOXA Nport 5110A Driver Failed Installation (On Linux Ubuntu 14.04)

Question

I am trying to install MOXA Nport 5110A Driver in my Linux Ubuntu 14.04, but failed miserably. The details about installation process is too long for me to understand where the problem is (and frankly I am still a noob in Linux world). The details is listed below.

Can you help me finding out where is the problem?

I attach the link to download the driver files here: NPort Real TTY Driver for Linux

Answer 1

To help anyone else with this problem, you need a MUCH later driver. As of Oct 2015 the latest driver is available from this link (Linux) moxa support forum link

Please remind Moxa tech support that it looks REALLY bad that the product they are selling has a 4 year old driver, not updated on their site!

Answer 2

I had the same problem and got in contact with MOXA. They managed to redirect me to the distributor (systerra in Germany). They (systerra) sent to me the driver version 1.18.51_build_15051816 which worked just fine. I asked MOXA to upload this version to their website as well, don't know if they managed so far.
