Q: Can I use version 32.00 on Windows 11?
A: Yes, but only by disabling driver signature enforcement and using the legacy installer. Microsoft does not recommend it for daily use.
Q: The driver installs, but my serial device doesn’t respond. Why?
A: Version 32.00 disables certain high-speed modes on older chips. Lower your baud rate to 9600 or 19200 in your terminal software (PuTTY, Tera Term).
Q: I lost my installer. Is version 31.00 the same?
A: No. Version 31.00 (2019) lacks support for Windows 10 20H2’s USB stack, causing random disconnects. Always get version 32.00.
Q: My adapter has a PL-2303TA chip. Will this work?
A: Yes, but TA chips were frequently counterfeited. If you get Code 10 with v32.00, your chip is fake. Buy a genuine adapter from StarTech, Plugable, or ATEN.
