Common driver types
- USB-to-Serial chipset drivers — many inexpensive cables use chipsets like Prolific (PL2303), FTDI (FT232), CH340/CH341 (WCH), or occasionally Silicon Labs (CP210x). Installing the correct chipset driver makes the cable enumerate as a COM port.
- USB mass-storage / USB bootloader drivers — some download cables use a simpler protocol where the target device exposes flash as a removable drive or a specific vendor device class; these typically need no extra driver beyond the standard Windows mass-storage driver or a small vendor-supplied driver.
- Vendor-specific drivers — some devices or sellers supply a bespoke driver labeled for GEV189; these are usually wrappers around one of the common chipsets.
