Salah satu teknologi transfer data digital yang banyak digunakan saat ini adalah USB (Universal Serial Bus), terutama USB 2.0 atau yang disebut juga Hi-Speed USB.Sementara itu, dukungan harware dan software terhadap teknologi ini bakal semakin meluas dan sebentar lagi akan bisa dimanfaatkan oleh pengguna komputer secara umum.
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 K-H 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.
- SuperSpeed USB has a 5 Gbps signaling rate offering 10x performance increase over Hi-Speed USB.
- SuperSpeed USB is a Sync-N-Go technology that minimizes user wait-time.
- SuperSpeed USB will provide Optimized Power Efficiency.No device polling and lower active and idle power requirements.
- SuperSpeed USB is backwards compatible with USB 2.0. Devices interoperate with USB 2.0 platforms. Hosts support USB 2.0 legacy devices.
