You may want to try again.
6·1 year agoWhat’s the name of the show, though?
Probably not, if we’re speaking about the next adapter in the line. They both use 4 pins, and there are no active conversion in the adapter itself, it just connects the pins like this:
USB ↔ PS/2 +5V ↔ +5V D- ↔ D D+ ↔ CLK GND ↔ GNDSo, as long as next adapter is not doing something funny with PS/2 signals, it should be ok for bare USB 2.0 connection.
Might depend on where you were learning.
On paper, when I was learning Descartes’ coordibate system, we used Y as up and X as left-right. And when it was time to plot in 3D, we used Z to “extend” the plane into yourself and away from yourself.
You just hold your sheet of paper perpendicular to the ground (or just use a whiteboard) and it all makes sense.
Sometimes inline stuff is more readable.
Don’t worry, I’m quite sure your kind will find something to trip over eventually. No thing can be fully dumb-proof.
You can’t fix stupid.
A slight word of correction, looked at the pinning again, it won’t short circuit them, but one will try to charge the other. It will still be a fire hazard, just not as violent.
If you have two devices with female USB A ports that both provide power via said ports, connecting them with male-male cable
will create a short circut. Best case scenario: a current protecting fuse breaks the circuit. Worst case: both processors on both motherboards are dead.Better not think you can connect two computers with that evil thing. That’s why type B connector exists, it’s about the same size, but it never connects to a port that provides power.
The point is that manufacturers can screw up standards and being a symmetrical connector does not cure idiocy in the heads if some people. Yes, the standard explicitly says you have to short opposing data lines for 2.0, but that does not mean everybody will comply with it. (The author of the video is not an idiot, they just demonstrated that it’s possible)
The most common example of this I can think of right away is male-male connectors with type A USB. They are explicitly prohibited, yet many manufacturers create them and use in their products.
That’s why I said that no standard can protect you, you’re just relying on people not being dumb and actually reading the paper you published.
You don’t need to check female port orientation, it’s always the same, pins inside the port are looking at the board the connector is soldered to. Of course, unless manufacturer decided to do something funny, but no standard is protected from that.
Except it’s a proprietary piece of junk stuck on USB 3.1 (and I love my thunderbolt connectors too much to let it slide), that can’t offer proper power delivery because of power pin literally burning out.
The only thing they did good is fixing the need to check cable orientation before inserting it (yes, you don’t have to try three times, you can just actually use your eyes, USB-A connector’s orientations can easily be told apart just by two square thingies on each of it’s sides).
But as USB-C came out two years later, it wiped the floor with lightning. Anyone saying otherwise is either insane, didn’t read the specs or purposefully misleading you. And only now Apple is switching over. Freaking 7 years later. Though, not because they realize how inferior their connector is, but because they were made to.
If I ever have to write some kind of huge load balancer, I’ll do my best to call it “The Queen Bitch of the Universe”.
Because math works with Y up. Physics steal from math, engeneering steals from physics, so, here you are.
What I can’t get is imperial measurement system. Apparently, nobody but americans can. And that stuff is far worse than Y and Z switching places.

I think it’s around 9:04 of 7th episode.
