Here is a different troubleshooting procedure for serial ports on Linux:
Open a Terminal window and put in this command EXACTLY (except for the double quotes):
"while : ;do clear;ls -lt /dev|head;i=$((i+1));echo $i;sleep 1;done"
Press ENTER and watch the screen as you slowly plug/unplug the USB device, watching what device appears/disappears and record the name. If nothing appears/disappears your device is not loading a driver.
You will also need to enter the following command EXACTLY (except for the double quotes):
"sudo adduser ${USER} dialout"
(This assumes "dialout" is the group shown beside your device in the list above.)
Do not:
* Try to bypass group membership by running as root. That will create further problems.
* Try to change permissions of the serial port you see. They will be lost every time you plug/unplug/logout/reboot.
Then logout and back in again so the group membership takes effect.
Then go to JMRI Preferences->Connections and the device name you saw earlier should be in the dropdown list once you select a serial connection.

I installed 4.8 and everything seemed to work fine until I clicked the "finish" button, then it says it can't connect and makes me go back. I did everything in this page as instructed:
I also tried the instructions under "what do I do if my (USB) serial port isn't listed" on this page:
although I'm not even sure I did it right.
