I do not think you will get things like that anytime soon. It is said Intel will only have USB 3.0 PC chipset in 2011. So initially the support will be from other vendors like NEC. And there will not be so many peripherals available initially. http://xtreview.com/addcomment-id-10357-view-Intel-chipset-with-USB-3-in-20= 11.html > I still don't get it. =A0You'd have a tough time getting UART-like > devices to operate at even the top speeds of USB1.1 (~10Mbps), much > less USB2 High-speed (~400Mbps) I know that there are some JTAG debuggers which use FT2232C/D and the update to FT2232H improves the performance by quite a bit. The JTAG channel uses the MPSSE engine. The other channel can be used as JTAG or Serial. http://www.ftdichip.com/Products/FT2232H.htm Example: Amontec JTAGkey2 http://www.amontec.com/jtagkey2.shtml > The 5Gbps max rate of USB3 isn't a serial protocol; it's an deleted> microwave transmitter. =A0(I'm not sure I see the point of > USB3, given eSATA and ethernet. =A0But then I didn't really see the > point of USB2 when there was firewire, either. =A0I guess I'm just a > luddite...) With the support of vendors like Intel, I think USB 3 will be popular, beating Firewre finally to real niche. USB 3 will probably first used in mass storage like device.
