Tried to fix ports on Mac OS X Yosemite. Now nothing works I was having an issue very similar to this one:

Arduino compatible&#39;s serial port not showing Mac OSX

Basically I have a clone (VISduino) and it's made with a different USB chip so it needed a driver. Installing the driver didn't help.

Running:

 sudo nvram boot-args="kext-dev-mode=1"


didn't help. So I decided to delete Arduino and reinstall. Then I went through all of the steps again. 

Well.... now nothing works. Before doing this I could use:


Adafruit metro 
An uno clone 
My genuine uno
lightBlue Bean
adafruit trinket and trinket pro 
adafruit trinket pro via USB
digikey




I've reinstalled the drivers for these but NOTHING is working now. They were all working before. It just says Arduino Uno on COM1, or digikey on COM1 etc.



And of course my clone (vis duino) isn't working either.

How can I fix this? 



The com ports just are not there.
I solved this issue by deleting all of the Arduino files and the Arduino app. I put my sketched folder aside but deleted all libraries. 

Restarted the computer.

Installed Arduino fresh.

Restarted the computer.

Installed the drivers.

Ran the command.

Restarted the computer.

Restarted the computer.

Restarted the computer.

Then it worked.
