Intel Releases USB 3.0 Controller Interface Spec
hardsky submitted thrilling news about everyone's favorite interconnect cable by saying "USB 3.0 is set to deliver data-transfer speeds of up to 5Gb/s, initially over tweaked connectors and wiring and, later, over optical links."
Most UBB connectors have a USB symbol on one side which means (this side up). I'd never really thought about this until someone gave me an iPod. I then found that I was forever struggling to get the connector in.
What I concluded was happening was:
1. I'd sub-consciously worked out that the connector is inserted USB symbol up.
2. The Apple USB connector has the USB symbol on, but on the other side it has an Apple symbol.
3. My sub-conscious was in fact not distinguishing between USB symbol and Apple symbol. Instead the logic was something like, "that side has a symbol on, I'll put it facing upwards".
I'm quite sure that the "symbol faces up" convention is a part of the USB spec. I never needed to know this because my brain naturally worked it out without it ever entering my consciousness. This is a truly wonderful piece of human interface design and yet those morons from Apple go and break it with an inane piece of branding. Way to go Apple. Anyone who ever thinks that Apple cares about usability should think again.
While that is true, I showed that to my GF who is from Hong Kong and knows English as a second language, cannot do it at all, but she can read perfectly and a bit faster than me
it might be because the characters aren't normal for her, since english is my second language and it's not a problem at all, but I use the same set of letters.
There is a USB standards group, of which Intel has historically been the driving force. The various USB logos are trademarks of that group, so any "renegade" claiming to have USB 4.0 would be committing a trademark infringement if they tried to decorate it using recognized symbols and logos.
USB remains one of the great industry success stories, designed by Intel and then licensed out at extremely low prices with a very inclusive policy. USB gained as much traction as it did because Apple used to insist on upwards of $1 in royalties per chip implementing Firewire, on top of the difficulty of implementing Firewire in the first place. The margins on peripheral chipsets are so low that there was no way to manufacture cheap Firewire devices at those prices. They still want too much in royalties even today, which is why budget motherboards never include Firewire, and no low-end devices connect using Firewire. Ever seen a Firewire flash drive?
Meanwhile Intel understands the concept of a truly mass market, and designed a simpler standard that uses less silicon to implement and less money for permission to implement. The price is higher CPU usage, since USB chips don't do very much work. Then Intel was clever enough to grab a golden opportunity and create a higher speed extension to the standard that suddenly brought it squarely in contention with Firewire, while being totally backwards compatible. Firewire answered, with Firewire 400, but without USB pushing them, they probably wouldn't have bothered to create a higher speed Firewire. Now Firewire 800 is on its way out, but going up against USB 3 at up to 5X the speed, while still having liberal licensing terms. Is it any wonder that camcorder manufacturers are jumping ship and abandoning Firewire?
