Building Windows 8 - Building robust USB 3.0 support

Posted by sumeethevans on August 23 2011, 3:26 AM. Posted in Windows.Next.

One of the important roles Windows plays as part of a broad ecosystem is developing support for new hardware. This is a pretty involved process and so for this post we wanted to take a look at supporting USB 3.0, something we know everyone is anxious to be using because of the improvements it brings. This is also our first video post – we aimed for "engineering" videos and not high production values but I think we make our point (note videos are embedded in HTML5 and available for download). If you're like me when looking at the video, you might think that those file copy progress indicators are looking a bit dated…stay tuned.

With throughput up to 10 times faster than USB 2.0 and improved power management that results in longer battery life, USB 3.0 introduces compelling reasons to improve the world’s most popular PC interface. By 2015, all new PCs are expected to offer USB 3.0 ports, and over 2 billion new "SuperSpeed" USB devices will be sold in that year alone.

Perhaps the most important aspect of USB 3.0 is the expectation that customers have of USB: it’s just USB3 so it should just work, right? Each and every USB device, low, full, high, and SuperSpeed, has to work in Windows 8. That's our focus while also delivering the most robust and reliable USB stack.

Let's take a look at USB 3.0 in action as it takes on some pretty significant copy tasks and races against USB 2.0.
