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

I love the extra current. 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.

Yep I've seen that too.

Not all of my USB 2 devices will work on a USB3 connection

Hi Philo,

You are correct in theory. 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.

Well, so far none of the people I deal with have burned out USB ports...


From what I've seen , they might not be able to be able to plug in a
USB device

As you shouldn't. It's nice that there's a new port but until a lot of
devices which take advantage of it come out, it won't be too useful...
kind of like Thunderbolt.

Considering how USB 1.1. 2.0 and 3.0 made sure to retain compatibility
and therefore ensured that USB became ubiquitous, I can imagine that 3.1
will have a hard time gaining in popularity.

Did you see my write up on PCIe USB cards over on the W7

I might have seen that. So far, in all the machines I work on I've never
had to add a PCIe USB card.

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.

OTOH: When it comes to backing up large amounts of data, at least USB
3.0 will come in handly

It's called USB "C" I thought. And no, the OEM's are not done configuring
which services they will offer with it at first. I know HP is going to limit
theirs to 15W for the 1st year. I don't know if they are going to include HD
video & audio with it this year yet.

Yep, we'll be seeing nothing exciting this year come from it. It will be able
to "quick charge" a cell phone though. Whoopee!

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.
