USB Is A Lie

[@Watchandlearn91]

The very fact that they took existing specs and rebranded them is just insane. For example, taking USB 3.0 and rebranding it as USB 3.1 Gen 1 and then rebranding that same spec again as USB 3.2 Gen 1. Sure, they claim they are trying to make things more transparent for the consumer with USB4 since it has to be type C and 20gbps or 40gbps but just you wait until they make USB 4 Gen 1x2 or some BS rebranding for an older spec.

@@SmallSpoonBrigade USB 2.0 controllers can run on slower clock speeds to support 1.0/1.1 devices, this has been built into every USB 2.0 controller. Up until USB 3.0, USB used just two differential wires (D+ and D-) to transmit data, USB 3.0 (or USB 3.2 Gen 1 as I think it's called now...) introduced two extra pairs for more bandwidth. The available USB type depends on many things, including the USB controller, the USB device, the cabling, ports, USB hubs in between etc. For instance you can have a USB C cable that only connects VBUS, GND, D+ and D-, connect it to the latest USB port and it will only support up to USB 2.0 (or lower).

[@BeatsbyVegas]

there are usb c cables that are even 2.0 speeds of just 480mbps. You usually see these as the cheapest usb c charging cables for sale on amazon. The manufacturer assumes they will only be used for charging and thus cheap out by limiting it to usb 2.0 speeds.

[@drkastenbrot]

USB 2.0 only needs 4 conductors, 3 if you cheap out and use the shield as ground. USB 3 adds another 5 conductors, bringing the total to 9. Additionally, USB 2 is relatively slow and tends to work fine without shielding, while USB 3 absolutely needs shielding. So there is quite a bit of cost to be saved by making it USB 2 only. Some included charging cables even go a step further and have only the two power lines, so they can only be used for charging.

[@BeatsbyVegas]

@@drkastenbrot makes sense that a lot of the cheaper usb c cables are usb 2.0 especially the longer ones like 10 feet as having literally less than half the conductors adds up through a 10 foot (~3m) length. From my experience charging only cables are less common/ less highly promoted or rated on a storefront because a lot of people will occasionally use the charging cable to plug it into a computer and if it connects even at usb 2.0 speed the average consumer really would never know the difference. But if they plug it in only for their device not to be detected by their computer they may think the cable is faulty not realizing its power only.

You can thank Intel for some of the USB chaos. In the beginning there was Firewire. It was fast and it was easier than SCSI. Than there came along USB that was a replacement of the aging old RS232 and LPT ports. It had a lot of manufacture input but Intel was a major contributor. Apple wanting to move away from Firewire worked with Intel to come up with Thunderbolt. It was fast. Worked flawless for sound and video and you could break off USB ports from it. This allowed you to plug your mouse and keyboard into your monitor. And your monitor had a single cable going to your computer. USB at this time was going from a progression of slow peripheral things (still much faster than RS232) to higher and higher speeds. Every time the speed was bumped up the manufactures of different gadgets to plugin to USB would jump at the chance to go faster. NOW today, we are in the day and age of where Thunderbolt is being merged in with USB. The confusing part is... they are somewhat interchangeable AS IN... a Thunderbolt port connection can do anything USB C can. BUT a USB C port can't do all the things a Thunderbolt port can do. THIS would have been a good time to use a little color coding. Did they? NOPE. Do they document what the port actually is? Rarely. For the most part on packaging, it's all "USB C" good luck with knowing what it can do!

[@BReal-10EC]

[@SmallSpoonBrigade]

Yes and when PC97 was standardized, they even added color coding to help with that. It was kind of overkill as it was mostly the mouse and keyboard ports that looked the same, but still nice and helpful. You could tell even the most ignorant of end user to plug the cable into the port of the appropriate color and the only bad things that could happen would be if they damaged the pins trying to insert it upside down, or swap the keyboard for mouse as those parts were more or less the same. It's been quite a while, so I don't even remember if that mattered after the computer booted.

I thought the same at first too but since getting the proper cable, it works as expected and no longer has errors. Fastboot and ADB also behave as they should now whereas Fastboot would lose connection way, way too often with the older cable. Its quite a nieche though... but that didnt make finding the right cable any easier and I probably overpaid for it x.x

I could see a software that lets you know when you got a mismatch and then points to a compliant port if your computer has one. This would be based upon the hardware you currently have plugged in and could even recommend moving some connectors around to optimize the situation.

I can see the USB-C connector taking over when everything starts supporting only USB 4.0. USB 3.0 was a stop gap, where the USB-C connector was optional. I think many devices will still try to be USB 2.0 or USB 3 for a long time becuase of cost and easy backwards compatibility.

It's not even a bus (not the schoolbus type... the electrical type) but a point to point architecture... It is (originally) serial though, but even that is not fully true anymore as since USB 3.0 they use multiple pairs (parallel) to speed things up, so 'not-very-universal serial and parallel point to point' would be the new name... Also, the universal refers to the origins of USB, when it replaced gameport, serial, parallel and a few more obsolete ports I've forgotten about, it became 1 universal connector for all those things, universal doesn't refer to the 'bus' Also, USB is not electrically compatible, starting from USB 3.0, it uses multiple pairs making it electrically incompatible with USB 2.0 and older, requiring weird and bulky combined connectors. Same for voltage, used to be 5VDC, but can now be up to 38VDC I think with some power delivery modes...

One of the things that pisses me off THE MOST about USB is the power delivery. Prime example: smartphones and tablets.

And apparently there are NO hubs / docks etc out there that support power delivery for the DEVICES -- they support it for the host only.

The "universal" part of USB is that pretty much any device using any USB port can communicate to anything else using USB, regardless of when that port was made or what device it's on. A USB 2.0 and a USB 3.0 2x2 can communicate just fine, just at 2.0 speeds. I'm pretty sure even 1.1 is perfectly compatible. And that's true regardless of the port type (mini, micro, type A, B, C, etc). As long as you have a cable, you can get them to communicate. Before USB, that was not so true for devices that were very disparate! (phones, printers, computers, consoles, etc)

The "Universal" part was because at the time we had Gameports, PS2 ports, AT keyboard ports, Proprietary bus mice (that would only work on the card (eg an ATI card) they were attached to), DE9/DE25 serial ports, and parallel ports. It was not intended, originally, for storage devices, and more to the point it is STILL not intended for storage devices. UASP (USB Attached SCSI) hard drives, 4K WebCameras/Stereo webcams, and 24-bit/192khz Sound cards are all beyond the specification USB was intended for, as these devices all require their USB port to have NO other USB device on them, and even then, if something crashes the USB bus, it takes down all these devices with it.
