USB I/O Targets in UMDF
Warning
UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2.
The archived UMDF 1 samples can be found in the Windows 11, version 22H2 - May 2022 Driver Samples Update.
For more info, see Getting Started with UMDF.
Each universal serial bus (USB) device, and each pipe that a USB device interface supports, has a separate I/O target. I/O that the USB device processes is sent to the device's I/O target. I/O that a specific pipe processes is sent to that pipe's I/O target.
