Configuring the FTDI UART for use on Mojave
The FTDI drivers don't appear to be required any more but the Apple driver (/System/Library/Extensions/AppleUSBFTDI.kext) doesn't work out of the box with my particular device. Cribbing from these instructions:
Obtain the product and vendor ID for the device by checking out the USB section of System Profiler
I put the Product and VendorID into one of the entries in Info.plist and restarted the driver with:
$ sudo kextunload /System/Library/Extensions/FTDIUSBSerialDriver.kext/ $ sudo kextload -b com.apple.driver.AppleUSBFTDI
The information in Systems Profiler was as follows: ``` SheevaPlug JTAGKey FT2232D B:
Product ID: 0x9e8f Vendor ID: 0x9e88 Version: 5.00 Serial Number: FTY2MXT4 Speed: Up to 12Mb/sec Manufacturer: FTDI Location ID: 0x14200000 / 9 Current Available (mA): 500 Current Required (mA): 0 Extra Operating Current (mA): 0 ```
The Product and Vendor IDs need to be converted from Hex to Decimal. Editing the configuration file at /System/Library/Extensions/AppleUSBFTDI.kext/Contents/Info.plist as to change one entry with those numbers. I changed it as follows:
[...] </dict> <key>AppleUSBEFTDI-FT2232HQ-1</key> <dict> <key>CFBundleIdentifier</key> <string>com.apple.driver.AppleUSBFTDI</string> <key>IOClass</key> <string>AppleUSBFTDI</string> <key>IOProviderClass</key> <string>IOUSBHostInterface</string> <key>bConfigurationValue</key> <integer>1</integer> <key>bInterfaceNumber</key> <integer>1</integer> <key>idProduct</key> <integer>40591</integer> <key>idVendor</key> <integer>40584</integer> </dict> [...]
Essentially, use the same configuration from the original article but now use the Apple usb driver.
