      More like do nothing. Sure if everyone follows spec nothing will break from using the wrong usb-c cable in the wrong usb-c port but it’s common to end in a situation were literally nothing happens.

        USB-c manages all those protocols when you plug it in.

        It will always pick the best one depending on the available hardware.

          Yes, but I’m pointing out how the cable is part of it in ways that wasn’t true for many older standards. So if I plug a non-data cable into a data USB-c port (say a digital camera with AAA / LR6 batteries) into a computers USB-C port then nothing happens. Same if I try to charge the camera by plugging it into a USB-c wall plug. Or if try to plug my phone into the USB-c charging port on my laptop, no matter the cable since neither phone nor laptop has the function to charge other devices. Etc etc.

          I work IT and while I don’t work directly in support anymore I still get people at the office coming to me for support because I used to and we’ve outsourced it now. So I know first hand how confusing USB-C is to average users.

            Even if you use a data cable, it might not have the pins/wires for usb 1.1 fallback meaning a keyboard or mouse won’t work with it. Or it might support low power only. I had to buy a usbc cable tester to validate which ones might actually work with what.

            My favorite is that not all chargers support all voltages. I have a few that do 5v, 9v, and 20v, but if your device asks for 12v, you’re out of luck, you either don’t get anything, or it fails back to 9v which isn’t enough to accomplish what the device wants to do (like charge). Still, it’s standards compliant!

            The standard explicitly allows but doesn’t require support of any subset of standards so you never REALLY know what that cable or charger in your hand or the devices you’re holding can actually do without finding specs in docs… It’s really infuriating. The idea of USB-C is better than the reality, which makes the push to standardize on the connector not nearly as cool as it could be.

              I have a portable switch dock (it’s the size of a small power brick) and the cable that came with it broke. Finding a cable that supports the exact spec that the Switch needs to both get enough power to put it into docked mode and transmit the video signal took a few tries.

          Plug a USB-C screen into a USB-C port. Will it work?

          Maybe? If the manufacturer has wired the port to the GPU for DP/HDMI alt mode it might.

          … but you’ve used this display on this laptop before?

          Try another port! Nope, still nothing.

          Maybe it’s the cable? Rummage around through your cables and try a few out. Hope you don’t have any from the 2010s because there’s a good chance they’ll ruin your device.

          The screen works! But performance is terrible, why? It’s running in DisplayLink mode.

          You give up and suffer through.

          The most common thing I see is people confusing usb-c with thunderbolt, and using the former on docks and expecting it to provide power and transmit data.

        Sometimes they were. And cables weren’t, so if you didn’t know any better you’d be plugging your headphones into Line Out. And good luck telling blue and green apart in low light while wedged between the desk and the wall.

          Yeah. Haha! To be more fair, the top character in this chart should be trying to figure it out by feel, while crunched under a desk, and getting blasted by line noise.

    I have an ingenious system for this: I put my 20 Usb c cables in a box and if I want to transfer data to one of my devices I try a couple of cables from the magic box until it works.

      I must be living under a rock because this is the first I’ve heard of USB 4. Is it just a speed bump or does it affect the type of data that can be transferred? In my experience I’ve had issues using a usb 2.0 flash drive to use a live image of a Linux iso in a 3.1 port

        It bumps the speed and officially supports Displayport and PCIe protocols being tunneled through.

        Also, as a tiny nit for seemingly no other reason than to piss us all off, they have decided the “correct” way to write it is “USB4” (no space). This is in contrast to every previous version of USB such as “USB 3” (space).

    Apple can’t catch a break. Either they didn’t do anything to help USB c come to market or they caused the massive pita that is the USB c spec.

    My colleague was terrified that she lost her drive files for this exact reason. Had a USB-C cable, needed a Thunderbolt cable.

    2004:

    User: “I moved my PC to another desk and now my monitor is off. The hard drive is making noises though. All the power cables are in haha. I made sure the connections were all nice and tight it’s a bit strange.”

    IT: “Okay I want you to follow the video cable from the monitor to the hard drive. It should have a BLUE connector at the end.Can you see the label where it is plugged in?”

    User: “…yes it says ‘serial’, I think?”

    IT: “Aha. I’ll drop around this afternoon with a spare monitor. That Trinitron monitor you’ve got will need to go away to be repaired.”
