USB 3.1 ???

The dumbest thing about USB was simply plugging it in. The reversibility seems like a bigger breakthrough than the speed. Agreed. It's a shame that it breaks compatibility though. Since it's new, I will probably not be using it for a few years. Seems to me like is will be "adapter hell" for a few years too So far I am only now slowly converting to USB 3.0 |

No more worrying about burning our motherboards from over current on USB devices. And I love the extra speed. I don't love that some USB2 devices won't work on USB3, such as APC's UPS data cables. |

Theoretically the mobo would not burn out...it's simply a matter of the current being regulated not to exceed 500ma. That said: not all mobos are equal. I have an external USB hard drive that has two USB connections as it requires over 500 ma. It works fine on some of my machines but not on others. And I love the extra speed. I don't love that some USB2 devices won't work on USB3, such as APC's UPS data cables. Yep I've seen that too. Not all of my USB 2 devices will work on a USB3 connection |

In practice, no one will pay the extra 1/2 cent for decent sized traces to handle the current and circuitry to log out over load offenders. From what I can tell, it is 400ma combined max on all the ports. And you burn one port out, you burn them all out. To cope with this, I like to add a powered (directly from the power supply) "front panel hub" (Star Tech or Siig). I tell my customer's it is their "abuse it ports". They can plug their iPhone and whatever else they want into it for charging etc.. So far so good. I have only lost one front panel hub. But it did its job and protected the motherboard. (This customer was abusive of his equipment, so it was expected.) Had one customer who liked to jog at lunch to work off stress. He liked to listen to music while he tormented himself (jogging). So, his family chipped in for his birthday and got him an iPod. He didn't read the directions that said not to charge it off a computer. He burned out *ALL* the USB ports on his laptop. Then, without asking me, he brought it to Best Buy for repair. He did not realize that laptops are no longer repaired. They are replaced. Got back a brand new laptop with a brand new hard drive. He lost everything, including a lot of sensitive customer data. (I remove the hard drives before letting the customer return for replacement.) Yikes all the way around. Have you heard of a disease called CABDs? (Cheap Asses Buzzard Disease. The "B" might not stand for "Buzzard".) Causes so many USB problems. -T |

If I get a really old machine it's more a matter of adding a PCI USB-2 card...but most machines that old, have been phased out by now. |

I don't know if they are going to include HD video & audio with it this year yet. |

Give it two or three years, and maybe we can have a meaningful conversation about it. Yep, we'll be seeing nothing exciting this year come from it. It will be able to "quick charge" a cell phone though. Whoopee! |

I don't know if they are going to include HD video & audio with it this year yet. The Type-C connector is quite flexible. http://cdn.arstechnica.net/wp-conten...ut-980x735.png It has enough pins for a four pin USB2 as well as a five pin USB3 section. So logically, it has the same pins available as an existing blue USB3 connector port on your computer. Using the connector, I could build a computer and offer on the type C: 1) Just USB2 2) USB2 + USB3.0 (if prototype USB3.1 host chips aren't available) 3) USB2 + USB3.1 (fanboi version, first enthusiast motherboards with it) It will support the same old negotiation phases, so if no USB3 pins touch or are available, it can run as plain old USB2. The USB2 part should always work. What they do with the other pins, is adjustable. You could even have a special adapter cable, that just disconnects any of the USB3 diff pair connections, to "force" USB2. Or maybe adapter dongles will be available, "Type-C to USB2 only" dongle. It's a possibility. HTH, Paul |

My understanding was that the spec was called "USB 3.1" and the connector that took advantage of it was a "USB C" connector. I could be wrong. |

Well, I agree with you - and what could be better proof than that? :-) Notice too that Paul in his post refers to the Type C connector and USB 3.1 and others being offered on a type C. -- Gene E.
