bonzify@airmail.cc submitted a question about your project, "Earth-friendly EOMA68 Computing Devices":
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".

What is Usb-C? just wondering?

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.

ya know, what i do is, i select all then delete by staring to write a reply without quoting previous posts ;)
To select all, on android: "tap and hold, then tap select all button"
The android email app, K9mail has a X button near quoted text when replying. taping the X button removes quoted msg.
Each email seams to have a id so its referenced to which email your replying to. so ya don’t need to quote text for people to know what your replying too because if people use the threaded email list view. they will see which email in a thread your one was a reply too :)
Sorry if ya already knew, thought if ya or someone didn’t it might help :).
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:
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.
I never knew that - thanks!

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