What is the USBXpress Device Windows Driver?

The USBXpress driver is typically associated with devices that use the USBXpress USB-to-serial or USB-to-parallel interface. It's a type of driver provided by Nuvoton Technology (formerly by Cypress Semiconductor) for USB devices that communicate with a host system through a USB interface. The USBXpress driver enables your Windows computer to properly recognize and communicate with devices that utilize USB-to-serial or USB-to-parallel communication.

Common uses of USBXpress-based devices include:

• USB-to-serial adapters (such as those used to connect RS232/RS485 serial devices to a computer via USB).
• USB-to-parallel interfaces (for connecting parallel devices to a USB port).
• Embedded systems or microcontroller boards that utilize USB communication.

In short, the USBXpress driver allows Windows to interface with devices that use USB-to-serial or USB-to-parallel adapters.
