Retrieves memory handle from the requests and uses it to send a vendor command to the USB device. Marks the interface restricted so that it can be accessed by a privileged UWP device app.Д¬reates a default parallel queue to receive an IOCTL request to set bar graph display. Initializes the USB device by registering a EvtPrepareHardware callback. You can install, uninstall, disable, enable, suspend, and resume the system.Д¬reates a context with the WDFDEVICE object. Loads the driver and responds to PnP and Power events. This directory contains driver code that demonstrates the following functionality: Read/write start/stop events can be used to measure the time taken.ДЇor more information, see Unified Tracing later in this document. Invocation of the 're-enumerate device' IOCTL. Three events are targeted to the event log:ДЇailure to start the OSR device on a USB 1.1 controller. Included osrusbfx2.man, which describes events added.

Maximum packet size depends on speed (64 full speed, 512 high speed). The device does not change the values of the data it receives nor does it internally create any data. The device moves data from IN endpoint to OUT endpoint. One switch change can result in multiple bytes being sent.Д«its are in the reverse order of the labels on the pack (for example, bit 0x80 is labeled 1 on the pack).Д«ulk endpoints are configured for loopback: Sent on startup, resume from suspend, and whenever the switch pack setting changes.ДЇirmware does not de-bounce the switch pack.

Sends an 8-bit value that represents the state of the switches. It contains 1 interface and 3 endpoints (Interrupt IN, Bulk Out, Bulk IN).ДЇirmware supports vendor commands to query or set LED Bar graph display and 7-segment LED display, and to query toggle switch states. The device is based on the development board supplied with the Cypress EZ-USB FX2 Development Kit (CY3681). It uses only APIs and DDIs that are included in OneCoreUAP. This sample builds a Universal Windows Driver. The driver and sample device metadata also works with the Custom driver access sample. The sample was written for the OSR USB-FX2 Learning Kit.

In the Windows Driver Kit (WDK), the osrusbfx2 sample demonstrates how to perform bulk and interrupt data transfers to an USB device. It includes a test app and sample device metadata. The kmdf_fx2 sample is a Kernel-Mode Driver Framework (KMDF) driver for the OSR USB-FX2 device.
