Arduino Serial Port Problem

Hello,

I have a problem that is preventing me from using my arduino. The serial port only gives me four options ,( /dev/tty.Bluetooth-PDA-Sync , /dev/cu.Bluetooth-PDA-Sync , /dev/tty.Bluetooth-Modem ,and /dev/cu.Bluetooth-Modem )none of them of work.Before this happened,I downloaded the library from "Make an Arduino Controlled Robot" and ever since I have had my serial port problem.Does anyone know how to fix this or know anything else that might have caused it.

Please write back soon,

Lucas,

I had a problem very similar on an Arduino compatible (built by me) and I have discovered some things.

Yosemite 10.9 (and OS X 10.10 and newer) requires a signed USB driver kext (kernel extension). You can find one on the FTDI web site here:
http://www.ftdichip.com/Drivers/VCP.htm
Use version 2.3 for 64-bit OS X 10.9 or later. Install and reboot. Plug in your Arduino, and the Terminal command:
/usr/sbin/kextstat | grep FTDI
This will tell you if the FTDI VCP driver actually loaded. Also a /dev/tty.usbserial-xxxxxxxx entry should appear in your /dev directory.
If not,the Mac USB port isn't talking to your Arduino. So it's no use trying the Arduino IDE application.
Let me know if this workaround will work.

There was a similar problem with windows 8.1

The solution was to choose a Comm Port and then point to the Arduino driver.
This was much easier than ignoring unsigned drivers, etc.

I have not yet had the luck to paly with windows 8, but Mac has a linux oriented approach while Windows 8 I think it is different.

That's not exactly how I would phrase it ....

I can live with Windows 7 for quite some time.
