One SuperSpeed port for your old laptop

Fresco Logic ExpressCard

IDF We're not expecting to see SuperSpeed USB devices shown off in significant numbers until next year, but a few have turned up at Intel Developer Forum.

At the top of the list is Point Grey's 1080p HD webcam that uses the 5Gb/s USB 3.0 bus to stream the 60f/s picture data uncompressed.

Point Grey's camera uses USB 3.0 PCI Express-to-USB 3.0 chippery from semiconductor company Fresco Logic.

Fresco Logic's USB 3.0 ExpressCard: new ports for old

Of course, none of us have USB 3.0-compatible computers, and it may be some time before we get one. Can't wait? Then Fresco Logic also has an ExpressCard 34 add-in with a USB 3.0 port at the business end - and clearly room for a second one.

One port for now, room for another

NEC showed off its USB 3.0 host controller, a single-chip offering its was using to bridge an SSD's 3Gb/s Sata connection to USB 3.0. The hardware's not much to look at - and is just test kit, in any case - but the demo saw 500MB of data copy over in just over four seconds using USB 3.0 but almost 40 seconds with USB 2.0 - almost ten times as long.

NEC's chip is the first of its kind to be certified by the USB-SIG under it new device approval process.
