Huh, I don’t think I’ve ever seen a controller with more than 15 ports anyway. Usually looking through the device manager (or lspci) there are multiple USB controllers on a motherboard (mine has 4 for example) so theoretically you could do 60 ports. Also what can do you about chaining to hubs? Since technically the spec lets to chain up to 127 devices.
But the bigger question is, what in the world are you doing that’s requiring 15 ports.

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

Okay but what kind of application is it used for that you exceed 15 ports filled??

Don’t judge, I need this RAID 0 array of 30 flash drives for my workflow!

For my work, I personally have:
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.
I’d say its easy to hit 15 - thats only the USB devices attached to my work laptop.

Anyone who produces music with hardware and hasn’t spent the extra money to buy a dedicated MIDI interface.

It’s not actually that hard to get up there. Mechanical keyboard, wired mouse, external drives, headset, webcam, other peripherals, etc. And if you are trying to do anything more involved like music production, you end up needing way more (audio interfaces, midi controllers, etc.).

Off the top of my head: Sensors. E.g. in some underfunded university lab.

I helped run a Kickstarter where one of our rewards was Mac and PC software on custom USB sticks.
We had a couple hubs set up and cloned the drives 20 at a time.

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 don’t 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

I’m probably past that.

“so a typical PC motherboard destabilizes the system” you don’t say. Steve jobs killed the external Macos program they had for GSeries and m68k Mac’s when he came back saying internally “if you let competition thrive you cannot drive demand”.
so I think we can guess why it’s hard coded lol
