This High Speed USB to Serial Adapter supports data rates up to 230 Kbps up to twice the speed of a standard PC serial port. That means RS-232 devices should 'just work,' provided they are supported by the host operating system. Unlike many RS-232 adapters in its class, the Keyspan 19HS advanced drivers allow very high compatibility with nearly every RS-232 product on the market. The USB Serial Adapter is ideal for use with GPS, modems, digital cameras, ISDN terminal adapters, graphics tablets, PDAs, bar code scanners, label printers and other serial devices.

Looking for the best way to connect serial devices to a computer's USB port? Tripp Lite Keyspan's High Speed USB Serial Adapter provides a simple, inexpensive, and reliable way to make this connection. Probably also Monterey 12 and Ventura 13? I'll check if you say you're having problems.Tripp Lite Keyspan USB to Serial Adapter 1 Port High Speed RS-232 The kext works for Mac OS X 10.6 Snow Leopard to macOS Big Sur 11. The pkg exists for these products on the Triplite website: Catalina or earlier macOS versions don't require confirmation in the Security preferences panel and don't require a restart. Use the Security preferences panel to allow the kext. Double check the version and copyright date using Get Info in the Finder. You can use Pacifist.app to extract the kext from the pkg file.

I installed the kext manually by itself without using the installer. I removed the kext and just use Serial.app which has built-in drivers for those adapters.
