USB-C is one of the worst things that ever happened to computers.


@tom the power source/sink negotiation is a clever idea right up until it encounters reality

although I'd think with a phone and a computer it shouldn't be *that* hard for them to know to negotiate it the expected way around, so it's still ridiculous that this can occur

@jess @tom I mean it's not that hard to pop up a thing saying "hey you wanna charge this thing or not?", my Android phone does it

@noiob @tom oh yeah, prompting would more or less solve the issue universally but

gotta have that "zero friction" ux, right?

@noiob @jess sorry but there is no way in hell i would EVER want my camera to charge ANYTHING. It's ridiculous that it's even a thing that can physically happen.

@tom @jess well yeah in this case it's absolutely ridiculous, but in the case of the Switch you could argue that charging a controller from the Switch is a valid use case

@tom @someonetellmetosleep @noiob @jess this might also have something to do with the fact the switch is notorious for having non-compliant USB-C ports and might just be ignoring the PD messages and deciding to pull power from the camera anyway?

@tom @Lyude @someonetellmetosleep @noiob @jess pfpt I thought I saw the word switch here but I must have misread something

@jess @tom hell, a very naïve approach that would be better than THIS shit would be…

camera: hi, I see you have USB PD! how much energy do you have? laptop: I have 50,000 mWh camera: I have 2,500 mWh, charge me plzkthx? laptop: k

the worst case is:

laptop: I have 1,000 mWh camera: I have 2,500 mWh, want a charge? laptop: yesplz

then the camera would charge the laptop, but only if the camera has more energy than the laptop
