This document defines and describes the implementation of version 2.0 of the Microsoft OS Descriptors. Microsoft OS 2.0 Descriptors Specification It includes a specification for the OS string descriptor, extended properties OS feature descriptor, and OS feature descriptors formats. This document introduces Microsoft OS descriptors. Microsoft OS 1.0 Descriptors Specification See Microsoft OS Descriptors for USB Devices.

Window retrieves that information by reading Microsoft OS descriptors, and uses it to install and configure the device without requiring any user interaction. IHVs typically must use Windows Update or media such as CDs to provide their users with a variety of device-specific information such as pictures, icons, and custom drivers.Īn IHV can use Microsoft OS descriptors to store the information in firmware instead of providing it separately. However, the types of information that those descriptors can contain is limited. In addition, the device can store class and vendor-specific descriptors. USB devices store standard descriptors in firmware for the device and its interfaces and endpoints. Read the post is to bring awareness to those subtle changes and enable device/firmware builders to easily determine the root cause of enumeration failures. Those modifications support new USB features and improve device enumeration performance. In Windows 8, we’ve made modifications in the USB driver stack in how the stack enumerates USB 2.1, 2.0, and 1.1 devices. USB 2.1, 2.0, 1.1 device enumeration changes in Windows 8
USB device enumeration processĪ detailed description of the enumeration process used by the Microsoft USB driver stack - starting from when the stack detects the presence of a device and indicates to the PnP manager that a new device has arrived. This section provides links for manufacturers of USB peripheral devices.
