Windows CE.NET driver for EZ-OTG(TM) and EZ-Host(TM) Controllers


Cypress introduces its new driver for Windows CE.NET v4.2, supporting the EZ-OTG and EZ-Host USB controllers. With driver support for one of the most popular embedded operating systems, Cypress makes designing a USB host-enabled product even easier. The driver supports both the host and peripheral modes of operation, and even provides support for the On-The-Go protocol.


Windows CE.NET supports the most common device classes, so you can connect to human interface device (HID) class devices (mice and keyboards), mass storage class devices (hard drives, NAND flash drives, MP3 players, and mass storage class compatible digital still cameras), and printers right out of the box.


Three build options of the driver are provided:

  • USB On-The-Go
  • USB Host only (supports multiple ports)
  • USB Peripheral only

These are pre-configured for the most common usage models. Source code and documentation are provided to make it simple to do further customization.

Hardware Description

This is a software download only. This driver was created with an Accelent development platform using the Intel PXA255 XScale processor.
