| Chip Family | Windows 11 Native Support | Recommended Driver Source | Notes | |-------------|----------------------------|---------------------------|-------| | | Excellent | FTDI’s official website (VCP drivers) | Most reliable. Works with Memory Integrity on. | | CP210x | Good (built-in inbox driver works) | Silicon Labs’ official installer | Inbox driver works for basic functions; full installer adds COM port numbering tools. | | CH340/341 | Good (after manual install) | WCH (Nanjing Qinheng) official site | No inbox driver. Must download. Works if driver is signed (post-2019 versions). | | Prolific PL2303 | Problematic | Prolific’s website (only for genuine, newer chips) | Avoid if possible. Many counterfeit chips are deliberately broken by Microsoft’s drivers. Check your chip’s version (PL2303HXD is okay; PL2303HX is dead). | | Generic (no-name) | Unknown | None | Often uses counterfeit CH340 or old Prolific chips.
