I have not upgraded to 10.15.4 yet, so what follows is based on 10.15.3.
The previous Apple supplied extension is no longer in /System/Library/Extensions. ?It is now part of DriverKit and is located at /System/Library/DriverExtensions/DriverKit.AppleUSBFTDI.dext. ?The Info.plist file does NOT have a product id entry for the LocoBuffer-USB.
Using the link provided by DaveH, I installed the 2.4.2 version. ?After the install, plugging in the LocoBuffer-USB resulted in no changes. ?I then used the About This Mac >> System Report. ?After selecting Software >> Extensions, I scrolled to the FTDI entry. ?The "Notarized" status was "Unknown" and the detail section indicated there was a signing error.
I then deleted the install using terminal.
cd /Library/Extensions
sudo rm -r FTDIUSBSerialDriver.kext?
Rather than using the FTDI website, I downloaded the LocoBuffer-USB drivers from RR-CirKits: ?
After extracting the DMG file from the download, I opened it and ran the package installer. ?Part way through the install a prompt occurs to set security settings.
After opening the security window, click on the lock, provide the credentials and the click on Allow. ?After the install completes, it should now be possible to use Dave's one line terminal command to see the?cu.usbserial-FTXZHHQF line come and go as the LocoBuffer-USB is plugged in and out.
A review of the system report confirms a good install.
