USB 3.2 is supported with the default Windows 10 USB drivers and in Linux kernels 4.18 and onwards. [71] [72] [73] In February 2019, USB-IF simplified the marketing guidelines by excluding Gen 1x2 mode and required the SuperSpeed trident logos to include maximum transfer speed. [74] [75]
The xHCI reduces the need for periodic device polling by allowing a USB 3.0 or later device to notify the host controller when it has data available to read, and moves the management of polling USB 2.0 and 1.1 devices that use interrupt transactions from the CPU-driven USB driver to the USB host controller.
USB 3.2, released in September 2017, [39] preserves existing USB 3.1 SuperSpeed and SuperSpeedPlus architectures and protocols and their respective operation modes, but introduces two additional SuperSpeedPlus operation modes (USB 3.2 Gen 1×2 and USB 3.2 Gen 2×2) with the new USB-C Fabric with signaling rates of 10 and 20 Gbit/s (raw data ...

Previously, the WDK was known as the Driver Development Kit (DDK) [4] and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista and added the following previously separated tools to the kit: Installable File System Kit (IFS Kit), Driver Test Manager (DTM), though DTM was later renamed and removed from WDK again.
Common device driver compatibility issues include: a 32-bit device driver is required for a 32-bit Windows operating system, and a 64-bit device driver is required for a 64-bit Windows operating system. 64-bit device drivers must be signed by Microsoft, because they run in kernel mode and have unrestricted access to the computer hardware. For ...
USB 3.0 SuperSpeed – host controller (xHCI) hardware support, no software overhead for out-of-order commands; USB 2.0 High-speed – enables command queuing in USB 2.0 drives; Streams were added to the USB 3.0 SuperSpeed protocol for supporting UAS out-of-order completions USB 3.0 host controller (xHCI) provides hardware support for streams
It requires a license from Intel. A USB controller using UHCI does little in hardware and requires a software UHCI driver to do much of the work of managing the USB bus. [2] It only supports 32-bit memory addressing, [4] so it requires an IOMMU or a computationally expensive bounce buffer to work with a 64-bit operating system.
