The SA9123L chipset is natively supported by the Linux kernel via the ch341 module. No additional driver download is needed. The SA9123L is a workhorse in the budget
USB 2.0 High-Speed compliant; supports USB Audio Class (UAC) 1.0 and 2.0. Specification USB 2
Unlike mainstream chips like the FTDI FT232 or the Silicon Labs CP2102, the SA9123L is a budget-friendly alternative. However, its drivers are not natively included in Windows, macOS, or Linux distributions. This leads to the dreaded "Device descriptor failed" or "Unknown USB Device" error in Device Manager until the correct SA9123L driver is installed.
