The xHCI (USB 3.0) host controller driver and initial support for USB 3.0 devices is now publicly available on my kernel.org git tree. Greg Kroah-Hartman has queued the patches for 2.6.31, so Linux users should have official USB 3.0 support around September 2009. This is impeccable timing, since NEC recently announced they’ll be producing 1 million xHCI PCI express add-in cards in September.
This means that Linux will be the first operating system with official USB 3.0 support. I’m working with Keve Gabbert (the OSV person in my group at Intel) to make sure that Linux distributions like Ubuntu and Red Hat pick up the xHCI driver. Advanced users can always compile their own kernel on a standard distro install.
I hope that some USB 3.0 vendors who have prototypes will test with my driver. Instructions on how to compile a kernel using my git tree will follow.
This is a giant project that I’ve been working on for the past year and a half. It’s gratifying to see the code finally released, and exciting to know that hardware is on its way.
