This is again a generalisation, unless you measure the DC on the USB bus you cannot say it is noisy or that some cheep industrial isolator will have cleaner USB 5Vs...
Hi and thanks a lot for the very helpful advice.
I am a little confused about the huge number of different standards
Why not simplify and reduce the number ?
Like pros tend to do. Ok. They do not have time to waste.
And also money to waste.
Thanks a lot again, gino
There is only 1 USB standard... Plug and play and works...
There are different flavours, USB 1 2 and 3 for speed as technology has advanced, different connector configurations for devices of differing sizes, I cant see a problem. Pro gear that uses USB (and a lot more do these days) has the same issues.....
Basically you plug in a USB cable and it works... It is a simplified serial bus interface that now due to the increased speed and flexibility allows it to be used for far greater things than its predecessors and is far easier to interface with.... In the past we had RS232 (still occasionally seen but again being replaced by USB and RS495. RS232 was USBs' predecessor as a general purpose serial interface, if you think USB is complex then you would cry if you had to interface to RS232, though it (rs232) was simplified over the years ending up with a reasonably standard interface based on a 9 way d-type connector.
USB.org - Welcome
I always recommend and try my self to keep things simple, don't look for complications because often they are not there... this is something that this hobby could do with in many instances, step back and ponder whether you are making things to complex, USB cables and the myths surrounding them is one illustration.... USB hubs and interfaces is another, they are often (99.99999999% of the time) addressing problems that aren't there, problems put forward often by those who have a motive to create and sell a fix for the non-problem, USB hubs are a shining example of that....

Hi and thanks a lot and sorry ... i meant this
are all these plugs REALLY needed ?
This is pure perversion. This is just a game to escalate entropy in the universe.
Why not 3 standards ... mini, midi e macro ? just select the best connector and it is done ... this is complete crazyness.
Question ... why a Type A and a Type B connector ? just take the best one and be with that.
And so on with the other ... too simple ?
Thanks and regards, gino

Hi ... i said 3 standards ... mini, midi e full size ... i think they could cover easily all the needs, if well designed of course.
In particular i find unnerving type A and B ... i do not know for sure but i think that maybe B is a better connector than A ?
why not use just the one better of the two ?
If you look on ebay there are thousands of different type adapters .. 😀
This is just not serious.

USB is universal. For everyone. From big servers to tiddly mp3 players. One connector cannot fit all. Over the last 20 or so years new connectors have evolved to deal with ongoing developments in both speed and small devices. It's called progress. In 1996 no one could have expected the iphone after all.
A and B are the 2 ends always have been A is the host B is the destination. nice and simple.

Ok it is me .. i fail to see the functional difference between a A and B type sorry.
What kind of issue B type addresses that A type cannot ?
I do not understand why on printers, for instance, type A cannot be used ... why on the earth ? is there a technical reason ?
Again ... what type B connectors gives that type A cannot give ? 🙄
or viceversa ... if one of the two is better than the other just stick with the better one.
I did not say keep one ... but not duplicate without need.

A and B was to stop idiots looping cables back on themselves. Just because you cannot understand a decision made by an industry group 20 years ago doesn't make it wrong. There are plenty of decisions made due to greed or attempts to corner the market but in this case it was a sensible concern given the knowledge of the average user at the time. Remember we were using win95 back then, or worse.

I did say there are different connectors for different devices, nothing complex about it, it is THE UNIVERSAL SERIAL BUS, and the different connectors are to cater for the ever increasing number of devices using USB and their shape and size, plug any USB into any USB and it will work.....
Now if we went back to RS-232 on a 25way d-type then maybe you would have something to moan about, because that was fun, hence the proliferation of RS-232 breakout boxes so you could eventually connect one bit of kit to another...

In fact even that is easy, play with D38999 connectors and the 1553 bus and you will soon loos the will to live, we are doing trying to sort a 25-46 shell will triax connectors from multiple manufacturers, bee4n at it for 3+ hours already!!!!!

Ok i googled and found something ...
What is the Difference between USB Type A and USB Type B Plug/Connector? - National Instruments
There is indeed a technical reason. My mistake.
I will shut up 😱

Hi and thanks for the explanation.
I just hope that designers will always keep in mind the KISS principle.
Just to make life easier to consumers.
There is indeed a company who have always had a great respect of not expert end users ... Apple.
I am sure this is one reason of their success.
Great company Apple. Even if they produce in China.

Firewire: apple only for years
iphone dock connector: apple only not compatible with anything else
Lighting connector: apple only needs adaptor to all your old apple docks etc
Thunderbolt: Apple only at the moment (but changing)
They are even abandoning headphone connectors. So Not sure how you can hold apple up as a shining example of not confusing people other than you can go to a shiny store and a genius will talk you through all the new cables you need?
Apple chose Firewire because at the time it was on practically every digital video camera. It was also the much better way dealing with streaming than usb. Not surprising as it was designed from the onset for that purpose while usb was designed to connect keyboards and mice.
Remember the first issue of usb 1.0 could not reliably stream cd-quality stereo (it got faster as cpu's got faster as it depends on it to run) while my FW400 (1st version) happily streams 24 channels (12 in, 12 out) of 24/96.
Thunderbolt is a retro-compatible upgrade of FireWire800.
FW is quite popular in pro circles and there are a LOT of DACs and ADCs using it because it is much more reliable than usb. I had my entire computer freeze up but the music still kept playing over FW without hiccups or drop outs.
The downside is that FW will always be more expensive than usb as it uses its own processor and is thus independent of the computers cpu.

Yes it is indeed and "exclusive" world, a closed system.
But when you accept to be part of the community it works.
Because it is very user friendly. Since ever. They have invented icons.
The have done of the user friendliness a mission.
And of course quality and performance are top notch.
Just think to T-bolt ... you can stream everything through it ... data, sound, video ...
Moreover, there are standards not used enough ... like rj45.
So much better than usb connector that is unbelievable.
Good up to 10 Gbit/s in the best execution.
What else is need for digital transfer i do not understand.
Locking mechanism. Cheap cables.
I want to tell you something.
Many designers want always to change, to invent something.
If we list the already available standards for difference purposes the list would be neverending.
And still that i have to invent something new, even if old standard can be perfectly fit for purpouse.
Because they have to invent something new. Always.
Thanks again, gino
Well to me apple is a hell of non-standard connectivity. I like open and I like standards. Apple is neither so gets none of my money. They invent to lock you in. But you bitch about USB then hold up apple as the right way to do it? This shows apple have a great marketing dept.
RJ45 is not a communication standard it is a registered form of a 8 pin modular connector...
I don't understand your problems with USB, plug it in and it works, even multiple plug ins with the smallest connectors (mobile phone charging is reliable)...
As to apple, I tend to disagree somewhat with your view, rip off prices, re-badged Samsung phones... sorry not into apple worship or worship of any other electronics or electronics based companies, far to much mythic for my liking...🙂

Hi and thanks a lot for the helpful advice.
I think that the real key is this
Pros need reliability and performance. I know for sure that many still are not comfortable with usb because they told me.
They are still using FW or T-bolt.
Thanks a lot again.

You forget that Apple has been the top choice of many many professionals.
In the audio-video sector almost the rule.
I am not an Applist at all ... i have only an old Mini Mac 2011.
But they are well designed and conceived.
