Can not connect to SSC-32U from a Mac

I’m using a Mac running MacOS 10.10. I’ve installed the FTDI drivers for the Mac, powered the SSC-32U, and plugged it into my USB port. But, I don’t see the USB device show up in the /dev directory.

I can plug in an Arduino with an FTDI into my Mac’s USB port and when I do, the device correctly shows up as /dev/tty.usbmodem1421 and I can successfully communicate with it, so I’m pretty sure my FTDI driver setup is fine on the Mac.

Any idea why the SSC-32U does not show up as a new device under /dev?

I just figured out the answer to my own question.

It turns out that the Apple provided built-in FTDI driver was getting in the way. Execute these commands to disable it:

cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns
sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled
