  2. Legacy Driver Incompatibility: Drivers designed for Windows 2000/XP use deprecated APIs or require 32-bit kernel access, which Windows 10 (especially 64-bit) restricts.
  3. Automatic Driver Overwrite: Even after manual installation, Windows Update may replace a working custom driver with a generic, non-functional one.
  4. COM Port Number Conflict: The cable may assign a high COM port number (e.g., COM20) that legacy software cannot see (often limited to COM1-4).
