Download the latest version of Keyspan Serial Assistant for Mac - OS X Drivers for Keyspan USB adapters. Read 14 user reviews of Keyspan Serial Assistant on MacUpdate. The USB-Serial adapter and software drivers are capable of providing a no-firmwarechange feature that enable USB interface to be transparent to serial port peripherals with minimum modifications. The only driver issues I've ever had with usb-serial adapters I've ever had were with MacOS. I think I got it narrowed down to the Prolific chipset in about 40% of them. That being said, the FTDI chipset is the most widely supported chipset in the world, is natively supported by all the OS's I know of, and simply works. Keyspan has updated its Mac OS X driver for the USB to serial adapters. Version 1.2 of the USB software fixes issues with the Classic environment crashing when quitting and some glitches with.

The driver for the cable can be downloaded from the Prolific website, however we have found an open source driver, which does the job and more over gives some better performance. We recommend you download the open source driver.

After you have installed the driver, connect your cable to any of your free USB ports. Mac OS X will automatically create a serial device, which can be found in /dev. Start a terminal session and list all available serial (or tty) devices available. Type the following:
ls -l /dev/tty*
Windows (ZIP)- Driver v3.4 (2016-09-27) Mac (ZIP)- Driver v1.5 (2018-07-04) Linux (ZIP)- Driver v1.5 (2018-03-18) USB-to-serial converters like the CH340 are great for uploading code to a microcontroller or viewing data from a GPS on a serial terminal.
Find the entry that is referring to your cable. Typically this should look similar to:
/dev/tty.PL2303-0002600D
Now that we have identified our new serial device, we can start connecting to a radio. Most people will use a Terminal Emulator, but as most of these programs were built pre-Leopard, you may find some difficulties running them on new(er) Mac hardware. We simply use the built-in screen program on Mac OS. So in the same terminal window, simply type:
screen /dev/tty.PL2303-0002600D 57600
You can obviously change the baud rate or any other options to what you need to connect to your specific device. Ten-Tec Omni-VII uses a baud rate of 57600. We did notice that every time you connect and re-connect the cable’s tty device id changes.
I’m on Mavericks (10.9.5) and fighting with a USB device with a “FT232R” chip (from FTDI) for USB to serial conversion.
It was not accessible in OS X (e.g. QuickTerm didn’t list it, only the Bluetooth Port + Modem).

Using an old Windows (in a Parallels VM on the same Mac) I could (and still can) access the device, switch it back and forth between OS X and Win, and send commands to it using a terminal SW.

In OS X it seems to be unknown, however, the USB Device Tree reports the FT232R USB UART correctly with Product ID and Vendor ID from FTDI.
But I want to get rid of the Win (VM) solution and installed the FTDI driver for Mac, didn’t work.
As suggested by FTDI for Mavericks

I have also disabled (renamed) the AppleUSBFTDI.kext, restarted and installed the FTDI driver (version 2.3, signed by Apple). The installer always tells me “success” but I still can’t see the driver /System/Library/Extensions/FTDIUSBSerialDriver.kext (should it be there?) and the device isn’t accessible from OS X.

I’ve tried again and again, there is no FTDI or USBSerial device listed in /dev when I plug it in or switch it back from Win - I guess because the (OS X) driver isn’t correctly installed?
