There is a lot of news coming out of the BUILD conference this week. In the realm of USB, we've released preliminary documentation of the USB 3.0 core drivers. Check out new architectural diagrams and client driver interfaces!
While we're at at it, the BUILD conference is also bringing you several USB-related sessions and pre-recorded videos. Check back later if a video is not present.
Note: Windows Developer Preview is a pre-beta version of Windows 8 for developers.
