Works flawlessly on MacOS Big Sur

After updating macOS to Big Sur, my TripLite Keyspan USB-to-serial adapter stopped working. The Big Sur requires signed drivers, while the Prolific UART chip in Keyspan does not. StarTech uses an FTDI chip and works right out of the box. No need to install any driver, just add a USB to USB-C adapter to plug it in and you're good to go.
