The problem that I have is that I have a ton of usb cords in my drawer. I DONT KNOW WHAT THEY ARE CAPABLE OF.
Is it a charge only cable (no data)? Is it usb3 5gbps ? Is it 100 watt power delivery? Is it thunderbolt 3/4/5?
- ethan_smith 1y agoColored electrical tape or heat shrink labels at both ends of each cable with a simple coding system (P=Power delivery wattage, D=Data speed, T=Thunderbolt) solves this problem permanently.
- ianburrell 1y agoThe USB IF really should have specified some labeling for cables. The icons used on USB-A connectors are too complicated. What I think would work well is colored rings, with some for the different USB3 speeds, and some for the 100W and 240W charging.
- whatever1 1y agoReally what we need as consumers are just 2 numbers: X GBps | Y Watts. I don’t need to know what freaking protocol it uses under the hood.
- mrheosuper 1y agoAnd that is what they are trying to do. For example: Usb 5Gbps is the same regardless of usb 3.0, 3.1 or 3.2 gen 1. In fact, customers dont need to know that "3.0" number. they just need their ports support 5gbps
- crote 1y agoThey did! [0] The problem is that the vast majority of manufacturers have chosen to just completely ignore it. [0]: https://www.usb.org/sites/default/files/usb_type-c_cable_logo_usage_guidelines_20240903.pdf https://www.usb.org/sites/default/files/usb_type-c_cable_log...
- raron 1y agoI think most of the cables are just not certified by USB alliance (?) so they can not use those logos.
- sidewndr46 1y agoAm I supposed to be an expert on international branding and trademark law just to determine what cable I need to use?
- jdlshore 1y agoDon’t be disingenuous. The branding guidelines are for manufacturers. Consumers just read the logo, which straightforwardly lists the speed and power capacity.
- sidewndr46 1y agoBut anyone can print up those labels and slap them on a cable. Or they could make ones that look really similar but aren't quite the same
- ncann 1y agoYou can test them to a certain extent using a USB tester device like RYKEN RK-X3
- CharlesW 1y agoYou need a tester like the FNIRSI FNB58 (not affilate link: https://www.amazon.com/gp/product/B0BJ253W31 https://www.amazon.com/gp/product/B0BJ253W31). This is just an example and not a personal recommendation, as I've just started looking into these myself.
- amelius 1y agoWhat I want is a tester that can show bit error rate.
- Gigachad 1y agoThunderbolt cables have always been marked either on the ends or with a sticker wrapped around the cable. Everything else can be assumed to be a 2.0 cable at 60w/140w
- miek 1y agoI printed details on labels using a Brother label printer and then attached them to one end of each cable.
- alanbernstein 1y agoDetails you found using a tester? I label some USB cables, but without a tester there is a limit to how much I know about them.
- Latty 1y agoThey have fixed this, the modern spec has speed and power rating logos that (good) manufacturers can put on the cables. Just assume anything without a logo on it is USB2/5v only and buy some new cables you know the specs of.
- MangoToupe 1y agoThe fact that cables have varying speed and power seems like a failure at launch. Who benefits from this? Manufacturers trying to save money on cables? Fuck that. This just means we'll use the cables that actually work everywhere to death and throw the rest out. What a waste.
- Latty 1y agoWell, there are always going to be varying speeds and power because needs change and tech improves, as the spec improves over time, the cables have to vary. Either you change the cables entirely (creating even more waste as now you have to change even if you don't need the higher spec), or you have varied ones. Also, right now they can do higher speeds at shorter lengths, but not longer ones, so if you had only one speed, you'd have to have a short maximum length, or pay for very expensive active cables for any long cable, even if you only need it for power. Even if it were purely cost, even then I think we still benefit: the alternative is cheaper devices will use a different cheaper cable spec, and you end up with many different cable types where you can't use them at all. Sure, maybe I won't get max speed from one cable, but still being able to get half speed and or power is better than a cable I can't use at all. Honestly, I just have never got this criticism, the alternative is just "have completely different cables" and that has literally all the same problems but worse, outside of "it can be hard to identify what this cable supports", which is solvable in much better ways than making them incompatible (as with the cable I'm looking at on my desk right now which explicitly says 40gbps/240w on it). I grew up in the era of every mobile phone having a different charger, and it was always a nightmare when you were at a friend's house and they didn't have the one you need. I may not get max charging speed, but now everyone always has a charger I can use for any of my devices. Please, I don't want to go back.
