[Arm-netbook] [Campaign Question] USB-C is used more and more...

[lkcl]

[cc'ing arm-netbooks as this question is best answered there, so that
other people benefit from it]

USB-C is used more and more often in a day to day basis.Thunderbolt-3, HDMI
ports and new tecnologies are frequently being used more often in the
mainstream market. USB C can intagrate these technologies and also repace the
charging port entirely. How come you didn't use USB C for the EOMA68?

there is no such thing as a physical item named "an EOMA68", as it is
a standard. the *option* to use USB-3 *is* actually on the EOMA68
standard. USB C is NOT part of the EOMA68 standard, because it would
be inappropriate to do so.

HOWEVER.

implementors of base boards are ENTIRELY AT LIBERTY to add a USB C
socket on the base board.

AND

implementors of Cards are ENTIRELY AT LIBERTY to add a USB C socket
on the user-facing end of the Card.

the reason why USB C was not included in the EOMA68-A20 - the first
in a SERIES of Cards is: massive redesign costs would be required to
do so. if you have around USD $20,000 spare, anywhere, i am happy to
do another SoC Card, one that uses a PMIC that supports USB-C.

I personally think there was nothing wrong with USB-A/B/mini-B. I put up
with USB Micro. I do *not* put up with USB-C. USB-C, in my not-so-humble
opinion (IMNSHO) is missing three letters off the end that, together, rhyme
with "map"...

No C for me.

they're fine for 0.5A, with some devices going up to 1.5 or even 2.0A
via various "schemes".

Quick phone top-post, sorry Luke.

Zap, I will presume for the moment that you have been living under a large
roundish lump of granite for the past year-and-a-half-plus (or perhaps in a
small cave in a particularly remote area) and that Creepy Uncle Google, for
whatever reason, is not working for you.

There is a protocol and a connector at work here. USB 3.1 would be the
protocol, theoretically even faster (and otherwise more capable) than
USB3.0. USB-C is the associated connector, and the two are inextricably
linked - AFAIK, one can *only* use the USB3.1 protocol over a rwo-connector
cable that has at least one end terminated in a USB-C connector.

USB-C is a rectangular-ish connector - its ends are circular but the area
in between is flat so it's not an oval shape. Not sure what the technical
term is - high school geometry was a long time ago indeed. At any rate, the
connector is a little larger than USB Micro. It contains a ridiculous
number of pins for its size... 19 IIRC, but that may be me getting confused
with HDMI and MiniHDMI...

The other thing about the connector is that it's reversible. You can plug
it in upside-down and it will match merrily along as if nothing was
different.

However, it is also yet another freakin' USB connector to keep track of and
require adapters for, and as such, it's completely redundant and
unnecessary. Everyone on earth has already done the USB-A
triple-plug-to-fit dance enough times to be used to it. I have no use for a
standard whose only meaningful advantage is one I don't care about and
whose actual effect is that I need to buy more effing adapters just to make
my stuff work the way it should OOTB.

Oh nice. I didn't know I could do that *blush*

I'll have to remember that. Thanks, man!

My understanding is that USB-C is supposed to phase out all USB-A and
USB-B connectors eventually so that there's only one type of USB plug.
I'm pretty sure it's not required for USB 3.1. You may be confusing USB
3.1 as a whole with certain aspects of it that require USB-C (basically
higher transfer speeds than normal USB 3.1, if I'm understanding correctly).

To be fair, USB-C does bring this Xkcd comic to mind:

https://xkcd.com/927/

But one noteworthy distinction is that the standards body behind USB-C
is intending to replace their own standards, not others' standards
(though it might have the nice side-effect of finally convincing Apple
to switch to USB rather than insisting on its proprietary "Lightning"
nonsense).

I suppose time will tell, though.

A quick note on the USB-A "rotate 3 times to insert" bit: If the device and
cable are actually compliant with the standard then there is no guessing or
flipping. The USB trident logo will be on the visible side of the cable
when it is inserted. This doesn't help for vertically oriented USB-A
connections where you could reasonably be viewing from either side but on
your laptop it should always go in first try when standard compliant
devices are used correctly.

What? Why? I just got yesterday my first USB c device and it's much more
convenient.
