The PNP0500 device on a portable Windows 10 installation is generally reliable if the underlying hardware provides a legacy COM port. However, due to the portable nature (changing hosts), it's often better to rely on USB-to-serial adapters ( PNP0501 ). If you must use native PNP0500 , force the driver installation, reserve a high COM number, and disable power management.

Windows keeps records of old, disconnected portable devices. These "ghost" drivers can conflict with newly connected hardware, forcing Windows to default to legacy IDs like PNP0500.
