Fuck firewire. Glad it's dead. USB C is the best thing to happen to peripherals since the mouse.

USB C is the best thing to happen to peripherals since the mouse.

I would agree with you if there were a simple way to tell what the USB-C cable I have in my hand can be used for without knowing beforehand. Otherwise, for example, I don't know whether the USB-C cable will charge my device or not. There should have been a simple way to label them for usage that was baked into the standard. As it is, the concept is terrific, but the execution can be extremely frustrating.

Hey that's a fair point. Funny how often good ideas are kneecapped by crap executions.

[–] NobodyElse@sh.itjust.works 40 points 1 year ago (1 children)

I’m pretty sure the phrase “kneecapped by crap executions” is in the USB working groups’s charter. It’s like one of their core guiding principles.

If anyone disagrees with this, the original USB spec was for a reversible connector and the only reason we didn't get to have that the whole time was because they wanted to increase profit margins.

[–] Excrubulent@slrpnk.net 19 points 1 year ago (1 children)

USB has always been reversible. In fact you have to reverse it at least 3 times before it'll FUCKING PLUG IN.

[–] disguy_ovahea@lemmy.world 6 points 1 year ago* (last edited 1 year ago) (1 children)

That’s the reason Apple released the Lightning connector. They pushed for several features for USB around 2010, including a reversible connector, but the USB-IF refused. Apple wanted USB-C, but couldn’t wait for the USB-IF to come to an agreement so they could replace the dated 20-pin connector.

Burn all the USBC cables with fire except PD. The top PD cable does everything the lower cable does.

[–] Janovich@lemmy.world 11 points 1 year ago

IDK I’ve had PD cables that looked good for a while but turns out their data rate was basically USB2. It seems no matter what rule of thumb I try there are always weird caveats.

No, I’m not bitter, why would you ask that?

[–] ripcord@lemmy.world 10 points 1 year ago (1 children)

There are many PD cables that are bad for doing data.

[–] disguy_ovahea@lemmy.world 8 points 1 year ago* (last edited 1 year ago) (3 children)

Correct. The other commenter is giving bad advice.

Both power delivery and bandwidth are backwards compatible, but they are independent specifications on USB-C cables. You can even get PD capable USB-C cables that don’t transmit data at all.

Also, that’s not true for Thunderbolt cables. Each of the 5 versions have specific data and power delivery minimum and maximum specifications.

You forgot thunderbolt and usb4 exists now

[–] rumba@lemmy.zip 5 points 1 year ago

You can buy a single cable that does 40GB and USB4 and charges at 240w.

Buying a basic, no-frills USB-C cable from a reputable tech manufacturer all but guarantees that it'll work for essentially any purpose. Of course the shoddy pack-in cables included with a cheap device purchase won't work well.

I replaced every USB-C-to-C or -A-to-C cable and brick in my house and carry bag with a very low cost Anker cable (except the ones that came with my Google products, those are fine), and now anything charges on any cable.

You wouldn't say that a razor sucked just because the cheap replacement blades you bought at the dollar store nicked your face, or that a pan was too confusing because the dog food you cooked in it didn't taste good. So too it is not the fault of USB-C that poorly manufactured charging bricks and cables exist. The standard still works; in fact, it works so well that unethical companies are flooding the market with crap.

[–] TORFdot0@lemmy.world 4 points 1 year ago (2 children)

Do not all USB C cables have the capability to do Power Delivery? I thought it was up to the port you plugged it in to support it?

[–] FlyingSquid@lemmy.world 8 points 1 year ago (1 children)

Nope. My daughter is notorious for mixing up cables when they come out of the brick. Some charge her tablet, some are for data transfer, some charge other devices but not her tablet. It's super confusing. I had to start labeling them for her.

[–] TORFdot0@lemmy.world 4 points 1 year ago (1 children)

Come to think of it, all the USB C cables I have are from phone and device chargers so I just took it for granted. Good to know. Thanks for sharing some knowledge with me

[–] InputZero@lemmy.world 8 points 1 year ago

USB-c cables can vary drastically. Power delivery alone ranges from less than 1 amp at 5 volts to over 5 amps at 20 volts. That's 5 watts of power on the low end to 100 watts of power on the high end and sometimes more. When a cable meant to run at 5 watts has over 100 watts of power run through, the wires get really hot and could catch fire. The charger typically needs to talk to a very small chip in the high power cables for the cables to say, yes I can handle the power. Really cheap chargers might just push that power out regardless. So while the USB-c form factor is the one plug to rule them all, the actual execution is a fucking mess.

Agreed. They should be labeled with the rating.

This little guy works wonders for me.

I agree with USB-C, but there are still a million USB-A devices I need to use, and I can't be bothered to buy adapters for all of them. And a USB hub is annoying.

Plus, having 1-2 USB-C ports only is never gonna be enough. If they are serious about it, why not have 5?

[–] HeartyOfGlass@lemm.ee 22 points 1 year ago

Yeah, I'd love at least one USB A type cause most of the peripherals I own use that.

[–] iopq@lemmy.world 4 points 1 year ago (5 children)

I bought some adaptors in China for around $0.50 each. It really isn't that big of a deal
