DanTDMits actually worse bc ports are counted twice for 2.0 & 3.0
someone is going to nerdsnipe me so i will add that technically its 15 registered ports per USB controller, so you can add a dongle and have more than 15. a mobo usually only has 1 USB controller for way more than 15 USB ports though, Apple added this arbitrary restriction for no reason since none of their devices have that many ports. so a typical PC motherboard just straight up destabilizes the system lmfao
WIZARD POPEš«Okay but what kind of application is it used for that you exceed 15 ports filled??
TrickDacybut why would you need [thing that is already technically possible and could conceivably be needed]???
Are you an apple dev?
Well, from an Apple pov, thereās no reason to change that limit (which is probably there because of some legacy limitation) until they release a device with more usb ports, which they probably wonāt. macOS isnāt supposed to run on your pc motherboard after all.
But I agree that itās annoying. I was daily driving a hackintosh with catalina for two years. Wasnāt the easiest setup.

Yeah, and from an Apple POV it makes sense to take away common ports just to make the phone .01mm thinner and sell you a shitty peripheral to replace the hardware port.
Doesnāt mean itās a good idea or something that people would accept from a company they didnāt have cult like devotion towards.
Iād argue though, there is a difference between a technical limitation apple just doesnāt care about resolving because it just doesnāt matter for any device their software is officially available on and them intentionally removing features.
Like, I donāt think the port limit was an executive decision but some random programmerās who wrote that code like 25 years ago when he decided that one byte must suffice for the total count of usb ports.

One byte is much larger than 15.
I am just asking what they are doing to need that as I cannot think of anything off the top of my head
I mean, itās pretty easy to imagine needing 10 USB ports. I think Iām using around that many myself on my desktop. Then just add a couple more for things that may be things needed temporarily.
I can hardly imagine needing 15 ports at the same time.
Well I am currently using about 5-6 ports on my PC and 2 of those are not really needed. I can imagine using a couple more but certainly not 15
The thing is though, every situation is different. Iām glad the designers of USB did not think like you do. Having the ability to use a lot of devices might be rare but itās definitely been needed before, whether or not others can imagine it.
Fuckās sake I was just asking what they were using it for that they filled out 15 ports and everyone is attacking me for thinking 15 is too much or something.
The question wasnāt a problem. The repeated implications that itās too many is obviously what annoyed people.
I never implied itās too many. I just said I cannot think of a way to use 15 ports (as in my personal setup). Might not have been the most clear but never implied it.
endlessedenmeanwhile Iām overhere withā¦
keyboard, mouse, camera, 4x flash drive, game controller, ebook reader, external storage disk, printer, VR headset, multimedia card reader, LED controller, my monitor (USBc display + hub + KVM) and my phoneā¦
ofcourse not all at the same time. but I have a mess of USB extensions and hubs as I donāt have enough root Ports lol
(Linux not hacintosh) I apparently couldnāt run it if I wanted to.
Yeah that was my main thing. It can be done but most people donāt need all of those plugged in constantly
My kids gaming pc tower has a set of usb ports on the back and a set on the front. Itās great to have options, but heās not going to use them all. Ie he has ten usb ports for the five he uses
Fair enough, but not everyone is your kid. Needing to have things plugged in at once shouldnāt need defending. I would prefer to leave things plugged in if I can. USB supports that, so why wouldnāt I?
Music production.
When I worked for Apple, I do remember the iOS devs having racks of iOS devices all being flashed at the same time off a single Mac. But I donāt remember the count and this was years agoālike Snow Leopard to El Cap era.
I was just kind of data analytics, but the labs were near my area, so canāt really give much more info, but mildly interesting, I guess?
one physical USB-A socket on the machine can read as two USB ports virtually due to one port supporting USB 2.0 and USB 3.0 at the same time, I believe its a backwards compat thing. I think there might also be internal USB ports as well but donāt quote me on that. On mobos with 8+ physical USB A sockets it can easily get past the 16 limit unless you specifically disable the USB 2.0 port, which then might break older devices relying on that and it becomes a whole headache. this person explains it better than I can
Ah I see. So itās more like plugging in 5-10 things exceeds the limit.
daggermoonIām probably past that.
With what though? Just curious
Hard drives, DVD/BD-ROM drives, game controllers, a floppy drive, webcam, charging cable, a scanner, thereās more iām probably forgetting.
And you have all those constantly plugged in? Iā probably hate the cable mess
A lot of that can be easily cable managed, most people just donāt bother with the effort of making it look nice.
Itās all behind my desk. Itāll be fine.
More realistic option is 15 other Logitech wireless device receivers, and you donāt know which one goes to your current mouse and keyboard, so you just leave them all plugged in.
At least, that is my experience working in IT. Personal record was 6.
That would make sense. Didnāt think of it.
For my work, I personally have:
- Webcam
- Mic
- Dongle for mouse
- Dongle for headset
- Wired keyboard
- Monitor 2 touchscreen
- Macropad
- Ethernet adapter 1 (connection to work network)
- Ethernet adapter 2 (connection to small switch with no uplinks, for device testing)
- Ethernet adapter 3 (connection to local avoip network)
- External drive
- Microcontroller programmer (universal, let me cut down on a few other adapters I had)
- Serial adapter
- Card reader
- Video capture - analog
- Video capture - digital
- Audio interface for xlr I/o and my good headphones
- NFC reader/writer
Then a couple of loose cables for connecting the random devices, like a tablet for adb purposes, DSLR, etc. Not including the built-in devices on the laptop which show up as USB devices, like the crappy built-in webcam, microsd only card reader in the worlds stupidest spot, etc.
Iād say its easy to hit 15 - thats only the USB devices attached to my work laptop.
Ok that was legit.
Do you had recommendations for powered USB 2 and 3 hubs that are decent quality? Iām so sick of plugging things in and they donāt have enough power.
Sabrent. Bit more money, but I like the ones with built in power switches per port (handy for testing disconnection events), and the build quality is solid. Power supplies they provide can be a bit bulky, but I mount them in my rack so its not really a problem for me.
Anker I like for their slimmer powered hubs, but those mostly sit in my laptop backpack, not the daily driver on my home office desk.
Thank you!
I see that getting one with a power adapter increases the price a decent amount. Do the models without an adapter at least have a connector so I can provide my own?
Depends on the model, so youāll have to take a look at each. The really big ones usually have a port rather than a captive cable, the smaller ones it varies wildly.
Anyone who produces music with hardware and hasnāt spent the extra money to buy a dedicated MIDI interface.
Donāt judge, I need this RAID 0 array of 30 flash drives for my workflow!
altkey (he\him)Video. If there is something mindlessly excessive, itās always video. And if you have tree leaves for budget, instead of slightly more expensive hardware controllers or PCIe cards that can combine multiple inputs and outputs, and do it right, you default to cheap usb dongles per device used, and compose them on software level. If you collect inputs from several devices and output these to something like displays on a scene, while also collecting audio from mics, DJ deck, and outputting these too, numbers add up quickly. This clownshow is further expanded by unreliable software, usb power, Microslop Windows in most cases - because pros use it or Mac, no penguins. I have no pride in greatly exceeding what some random PCs could predictably do, for fixing random errors here and there when USB and USB hubs hit their practical ceiling is just another level of Danteās hell, for all us time- and harware-restricted tinkerers.
socsaāso a typical PC motherboard destabilizes the systemā you donāt say. Steve jobs killed the external Macos program they had for GSeries and m68k Macās when he came back saying internally āif you let competition thrive you cannot drive demandā.
so I think we can guess why itās hard coded lol
