✨ SYNOPSIS ✨

Wanna compile this driver into the kernel? iconic. Drop these lines into your kernel configuration file:

💖 DESCRIPTION 💖

The ubsa driver provides support for the USB-to-RS232 Bridge chip used by a whole variety of serial adapters from Belkin and other vendors 🫶

The device is accessed through the ucom(4) driver, which makes it behave like a tty(4). cute, right? 😌
