OS X (intel) driver for Openport

[donour]

There is a bit of trickery to make the FTDI driver work with the openport. Their driver is configured by this file:

/System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Info.plist

It is basically just a big xml file with all the product id's and device names. Unforunately that file is only read during _installation_, not at driver load time. That means you must edit this file before installing the driver.

To do this you must

1) download the driver files (i.e. FTDIUSBSerialDriver.pkg). This file is sort of like an application bundle so you can examine the contents like it is a directory
2) unzip the data file: FTDIUSBSerialDriver.pkg/Contents/Resources/FTDIUSBSerialDriver.pax.gz
3) cpio extract the data from the .pax file
4) edit the resulting Info.plist.
5) re-cpio and gzip it.
6) install the new driver

If you don't understand the procedure I above, not to worry. FTDI will include the openport pid in the next driver release.

I'm hesitant, but here's my resulting .pkg file for a working driver. I take no responsibility for it's use. It's for reference only.

In other good news, FTDI claims that will have a Mac/D2xx driver in beta sometime soon.

cheers
