Anybody got the straight-scoop?
« on: October 12, 2007, 11:28:54 AM »
I'm gradually collecting quite an inventory of these puppies.

Can anyone tell me if, as long as the "plugs" at each end are identical, if what connects those plugs is equivalent?

Or, can I use them interchangeably, so I don't have to carry more than one when traveling?

There is one easily recognizable difference between some and the rest,  in my center drawer: some have a small cylinder surrounding the conductor a few inches from the "USB-end". The others: no such embellishment.

Is that anything other than some kind of overload protector, err sumthin'?

What does it "mean".

Many thanks

Years ago I had found a website for an outfit that sold cables and adapters of all kinds.
It had nice photographs and charts - which is what I think that you (and I) need.

My understanding from reading here and there is that the bump in the middle is for noise suppression.

Discussion of the "bump" and all sorts of info here:

http://www.velocityreviews.com/forums/t245...erent-uses.html

Some more general info here, RHP:

http://en.wikipedia.org/wiki/USB

This might help too:

I've always operated on the principal that if the end fits, we're good to go. wink.gif Seems to have worked so far. Though I should note that a USB 1.1 cable did NOT work with our USB 2.0 scanner - the Mac saw the scanner, it made it do it's first little burps and blips, but then the scanner just sat there with the "warmup lamp 1%" and completely froze VueScan and the Epson software. Switched to a USB 2.0 cable and voila! No problems at all. smile.gif

Wonderful. Thanks.

I see that those "bump" queries were started back in 2004. Ithink I started wondering about them about that time. It's just taken awhile to realize that, as usual, the answers are on TeeEss.

Buried in that range of answers over there (Velocity Reviews) was this link . . .Lotsa USB info here which I found interesting even those some of it was in Windozspeak.

Dick,

1) I understand the bump to be a way to grab hold of the cable and disconnect it from its socket.

2) There are two types of plug-socket combinations. a) the flat end that has six contacts, two for power. b) the square end kind which has only four contacts for devices tat need no power.

3) USB 1.1 cables used in a USB 2.0 environment will drop the USB 2.0 speed to that of USB 1.1. The cables are made differently and the USB 2.0 cable can handle higher speed (higher frequency) without loss.

You jest of course, Herr Dr. Professor.

The "stuff" (technical term) I read made references to "noise" control/reduction, ferrite cores to reduce "ringing", RFI "blobs", shielding, amplification, hi/low quality of cables . . . all separate from USB 1 vs 2 (which I see as irrelevant because they have, as far as I can see, quite different connectors.)

The question was "Are the cables with the can/bump/cylinder/whathaveyou and those that do not sport such an embellishment interchangeable?

I wish to carry one, only, if possible when I travel.

I'm satisfied that the answer is "Yes". but it's also now so very nice to know that it's for pulling out the connection. Not!

"bump" queries. . .

There has been a nice set of USB adapters and such in the Cyberguys catalog; although I don't have it here to look at and the website doesn't seem to have it!

"Adapting" has never been my concern.

Equivalence or substitutability (is that a word?) is/has been. I'm satisfied.

Interesting collection of aphorisms...adages...maxims?

Observations:

1. That's why I'm still running 7, 8 and 9 year old computers. smile.gif

2. Well, I once put a USB 2.0 PCI  card into my 9600 and it fit just fine. Only problem, USB 2.0 wasn't supported by that machine.

3.
  • ethylene glycol (antifreeze) is very sweet but deadly
  • honey can be contaminated with botulism
4. Cotton candy   yum.gif

5. In other words, the thing seen, felt, heard, tasted, etc. is the substance, not the thing that recognizes same? Most would agree.
Then again..."that mind receives in its inner life its truth and concrete essence, while in objectivity it is at home and reconciled with itself. The mind which has thus reverted to the substantiality with which it began is the mind which has returned out of the infinite opposition, and which consequently engenders and knows this its truth as thought and as a world of actual laws."  Hegel

This is fun. smile.gif
