intel usb 3.0 host controller adaptation driver

Sharp asserts that USB 3.0 support for Linux means having to adapt the Linux USB stack to the new device speed and develop a new driver for the xHCI host controller. And it is backward compatible so that you can continue to use it with USB 2.0 hardware. I expect this demo to be even faster when the device and host controller are implemented in silicon.' The new bus also provides better power management that leads to longer battery life. She was happy with the results: 'The demo showed speeds that were about 3.5 times faster than USB 2.0 high speed devices. 'My Linux xHCI driver is necessary to communicate with the USB 3.0 device through the xHCI host controller prototype,' she adds. In a video on her blog, Sharp demonstrates a USB 3.0 prototype from hardware provider Fresco Logic that runs under Linux.

I've been writing a Linux driver for xHCI (the new USB 3.0 host controller), and changing the Linux kernel stack to support USB 3.0 devices.' As she says, the wire speed will be 5 Gbps, while USB 2.0 languishes at 480 Mbps: 'Roughly speaking, it means that a file that takes 30 minutes to transfer over USB 2.0 could take 3 minutes to transfer under USB 3.0.' Intel developer Sarah Sharp describes her work on USB 3.0 in her recent blog with these words: 'Now that the bus specification is public, I can finally talk about the code.
