In the UK, due to cultural norms there is a slightly different standard for device connectivity known as "Universal Serial Double-Decker Bus" (USDDB).

A USB 3.0 connector on a cable with 2 layers.

@ipg i love sending my postcode files over USDDB

Himbeer

@ipg@wetdry.world Is this the USB 3.2 Gen 2x3 everyone is talking about?

Andy :aglaceon: :teapot_blush: #RIPYassie

@ipg where do I get these adapters? I'll need it for both ends.

snaprails

@andyy @ipg That's OK, they take a long time to arrive but then you always get two at once.

David Croyle

@ipg I suppose the data flows on "the wrong side" of the bus too.

Mark Johnson

@ipg They should have done this instead of the lumpy USB 3-B connector.

geekylou :transgender_flag:

@marxjohnson @ipg I thought that had one USB-B connector and two smaller USB-C connectors on it?

dodothedev :arch_linux:

@ipg @marxjohnson
I was about to reply "wtf you talking about!? I work in IT, and I've never seen a Double Decker USB!"

Then I got the joke. ๐Ÿ˜‚

Seth Junot

@ipg Did you know that in the UK the C in USB-C stands for Commonwealth?

Linh Pham

@seth Does the successor of Morris and British Leyland also get royalties from Mini USB ports and connectors?

@ipg

Seth Junot

@qlp @ipg

Yes! As an ode to their British heritage and Commonwealth influence, every time someone plugs in a Mini USB cable, a chorus of polite British voices exclaim, "Oh, jolly good! You've connected a Commonwealth-approved device! Cheerio!" The royalties are used to organize tea parties, distribute scones and clotted cream, and perhaps even hire a royal corgi as the official USB-C mascot.

snaprails

@qlp @seth @ipg Yeah, every time you use one BMW gets a cut.

mossfet

@ipg
i wonder why you never get double decker buses outside the uk

they're so good..
@alice

feliz

@mossfet They're quite common in Berlin too.

mossfet

@carl @feliz
this is the greatest bus i've ever seen

Carl

@mossfet Only to look at :-) very noisy and diesel-stinky
We got the first electric busses in Berlin now
@feliz

John Conway

@carl @feliz @mossfet Bus designer Jenkins had to think fast when he realised heโ€™d forgotten to leave room for the engine.

Rob Synnott

@mossfet @ipg @alice Most buses in Ireland are also double-decker ( Dublin Bus periodically tries articulated buses, then drops them when they get stuck on roundabouts). Articulated are arguably better if your roads can take them.

s0: Soldering Sorceress

@mossfet @ipg @alice we have some in Sydney on particular express routes

Vy-let

@s0 @ipg around here, if they want an express they just use an articulated bus

which gets me thinkingโ€ฆ

articulated double-decker? :blobcatthinkOwO:

s0: Soldering Sorceress

@vy @ipg we also have plenty of articulated ones. Double decker is used for that route because some roads canโ€™t accommodate articulated.

DELETED

@ipg we need a global universal standard if we want a world free of garbage and hoarders.

Victor Forberger

@ipg
I see the double decker makes it super speed. Yay!

๐Ÿ„ฟ ๐Ÿ…ท ๐Ÿ„ธ ๐Ÿ…ป

@ipg the better quality ones are in red, gold contacts are the cheaper variety.

Markus Peuhkuri

@ipg One is for hot bits and the other for cold bits?

MarjorieR

@metallcorn @ipg OK it's a double decker bus, but surely not a British double decker bus?
In the UK we measure torque in the very British (and SI) Newton, not the quaint American foot-pound.

metallcorn ๐Ÿง

@marjolica @ipg When I took this picture from the Internet I did not even pay attention to the text on the top, it was only the bus itself that mattered

Now I'm laughing, thank you.)

Ash

@ipg Each is andled a different way so it always works regardless which way you insert.
Or never works either way you plug it in.

quangobaud

@ipg
If you turn the picture upside down it looks like a goth Lego mummy. ๐Ÿ™ƒ

Jeremy Worrells

@ipg is it still subject to the USB Uncertainty Principle?

Will

@ipg There actually is something that looks kind of like this thatโ€™s a standard(ish) for use in Point of Sale systems called โ€œPoweredUSBโ€!

Back of a PC with 3 weirdo, tall USB-A like ports with red and cyan coloring
cleanycloth
@xanarin @ipg Dell also used a similar thing once for their laptop DVD drives (apologies for the crap quality)
Toad King

@xanarin @ipg plugging my phone into 24v usb to charge 5x as fast

Alany :verified:

@toadking @xanarin @ipg
It can be possible to make an adapter that converts the funky connector into USB-C PD 3.1

Will

@AlanyG21
Haha that would be awesome! Itโ€™s a perfect hacker project: itโ€™s technically interesting and challenging while being completely useless ๐Ÿ˜‚

rastilin

@xanarin @ipg

That looks horrific. USB-C does 100W anyway. I would have chosen an internal battery that constantly trickle charges to make up the difference, or a separate power supply, anything, literally anything, than a custom USB standard.

Jernej SimoncฬŒiฤ ๏ฟฝ

@rastilin @xanarin @ipg USB-C has been around for what โ€“ 6 years? These Point of Sale connectors have been around for around 20 years.

Eric Jennings

@rastilin @xanarin @ipg Before you knock PoweredUSB too much, remember that back around 99-00 when POS systems starting using it, the primary USB spec couldnโ€™t do more than 5V at 0.5A and USB-C was was over 15 years away.

These power devices that early USB just wasnโ€™t even interested in dealing with.

And even the 1.0 versions of the USB-PD specs at 20V 5A is less than the the 24V 6A PoweredUSB ports available 20 years ago. (Although most were 12V 1.5A plugs in my experience, I worked on POS software for a few years so had tons of test hardware). Itโ€™s really only been about 5-10 years since the main USB specification caught up with USB-PD 2.0. And for a lot of those years, implementations of USB-PD were really spotty and unreliable so the hardware manufacturers didnโ€™t have any motivation to move.

Plusโ€ฆ PoweredUSB also had the advantage of easily telling which way to plug it in, unlike a standard USB-A plug. For the late-90โ€™s, it was actually pretty nice.

@ipg Most other countries, of course, standardized on the Universal Serial Articulated Bus instead.

@Gaelan @ipg they managed to make micro USB even worse

Unacceptable. We need to put the โ€œUSโ€ back in โ€œUSBโ€!!!

Archie "Spanner" Eligius

@ipg This strongly reminds me of the Schrodinger's USB Cable problem. XD

Gorgeous na Shock!

@ipg OK you're joking but show the other end of the cable.

Bryan Veal

@ipg Does it need a special kind of driver?

socks

@ipg On the one hand, it's so cursed. On the other hand I'd imagine it feels great to hold in your fingers, like some fidget toy.

Breb

@ipg I hear that they are able to carry up to double the data rate of normal USBs too. Maybe USDDB should be a thing in more countries

Detour

@ipg I Looked Up USDDB On-Line To See If You Came Up With This Meme Or Not And Someone Had Already Reposted It On Reddit.

Chris

@ipg we briefly experimented with the Universal Serial Bendy-Bus (USBB) but this seemed like a better solution in the long run

Peter Gordon โœ…๏ธ

@ipg they tried to replace it briefly with the universal serial bendy bus, but dropped it due to insertion issues.

@ipg As a Brit, this made me chuckle ๐Ÿ˜„

@ipg This made me think of @NanoRaptor but now I see they've wiped out all their socials (not to mention their cursed tech photo edits) :( :( :(

zxm

@ipg and you can never find a cable when you need one. but when you do go looking you always find 2 cables :-)

pancake :verified:

@ipg @LunaRogue why not make it square with one more layer, this way we will have 4 different positions to try to plug it

@ipg@wetdry.world somebody make an edit that says "Fedi" instead of "Twitter" in the end of this video. /lh

@ipg being blue twice, does this mean this is USB6?

Meh as a Service

@ipg the I bet the polarity on the data lanes is also reversed

TrashMarine

@ipg the thing with this post is that somebody would 100% believe it if you posted it elsewhere

Pepijn Schmitz

@ipg _Please_ don't give the Tories ideas!

Ross of Ottawa

@ipg their square USDDB 'type B' connector is interesting. It's a grey-blue colour but not larger at all โ€“ all the extra contacts fit because it's bigger on the inside.

Manufactured by #tardis inc.

Kristoffer Lawson

@ipg an extra piece of trivia: when a new monarch is crowned, the second connector is turned the other way round. Meaning after a coronation you will need to renew your devices as the new connectors wonโ€™t fit in the old sockets, no matter how many times you turn them round. This is a tradition that dates back to the 19th century.

Raymond Russell

@ipg
I ordered a couple of these online...waited ages and two came along at once....

Robert "Anaerin" Johnston

@ipg And, of course, you have to attempt to insert it 4 times to get it in right.

@ipg I wouldn't be surprised if somewhere this would be in an actual product.

@ipg This is the one where the pins are on the other side, right?

@ipg i prefer the universal serial train. no potholes to deal with.

Avebury Rosetta :transistor:

@ipg Another fun UK fact: As a historical legacy, all communications ICs manufactured in the UK have little doors fabricated as MEMS systems. This is so when data arrives to the chip, it has to "knock" on the door. This is a reference to the State Opening of Parliament, where the House of Commons famously slams the door in the face of the Usher of the Black Rod. It's supposed to symbolise the idea the Commons are independent from the Sovereign, and goes back to when King Charles I tried to arrest five Members of Parliament, but was not let in.

Some question the practice of artificially enforcing an arbitrary ritual which does nothing but give the illusion of the controller being securely in the hands of the people who depend on it, but we don't manufacture many ICs ourselves anyway
