As we eagerly await the release of the most promising digital innovation for the future- Windows 8, there’s indeed a lot that all of us want to know and discuss about. The Immersive Browser and the Metro UI have by now garnered a great deal of appreciation from all sides; and all what we could say at this point of time is that, if the promises made by Microsoft come true, Windows 8 is sure to mark a watershed in the world of computers. Well, the latest news about the new OS is regarding the enhancements made with respect to its USB capabilities.
Support for USB 3.0
Windows 8 would be coming with a new driver stack that supports USB 3.0 devices. The driver stack is equipped with drivers that are loaded when a USB 3.0 device is attached to the xHCI host controller. Support for Static streams and the USB Generic Parent Driver (Usbccgp.sys), which implements ‘function suspend’ and remote feature wake-up features, are some of the new capabilities offered by the new driver stack.
As you might know, Windows 8 provides two types of boot support. You can either use the “Windows to Go” feature, which allows the OS to boot from a flash drive or an external drive. Whereas via an internal USB 3.0 UASP drive, there’s an option to build systems that boot from SuperSpeed USB 3.0 drives instead of SATA drives.
Moreover, the new OS comes with a new USB storage driver, which implements the USB Attached SCSI Protocol (UASP). According to official reports, the new driver utilizes static streams for bulk end points.
Improved Debugging and Diagnostics
Windows 8 comes with a couple of USB 3.0 debugging tools, that let you diagnose and fix USB issues much better. The USB 3.0 kernel
debugger extensions enable you to examine USB 3.0 host controller and device states. Moreover, the USB WPP and event tracing capabilities can be used to analyze USB interactions and troubleshoot issues with USB device issues all the more easily.
USB-specific Failure Messages
As far as troubleshooting is concerned, error messages hold the key to resolution. And Microsoft has rightly included new USB-specific failure messages in the Device Manager option, to make things really easier for us. When issues such as ‘enumeration failure’ occur, the General tab in Device Manager would display a USB-specific error message that indicates the reason for the fault.
Well, that’s all for now about Windows 8 drivers.
