How many USB devices can be plugged into a PC at one time? It’s a reasonable question, but the answer is more complicated than you might expect. We took 127 USB devices and plugged them in one by one until something broke. Then we took those same devices and reconfigured a few things to see if we can break it a different way. Just how broken do things get? Which limits get hit? How can you calculate YOUR maximum USB amount?

Best take away is just get an AMD
AMD
Whos castle is this😂
errr.. correct me if am wrong. but the drive letter limit in windows isnt a thing anymore.. the drive letter stuff is just leggacy crap from dos.
dont get my wrong I dont think its particularly compatible with stuff as most things look for a drive letter not an address but still windows should just crack on from that i understand.
My dad once gave me a 4-port USB hub that was 2.0, mandatory powered, and had the same connector printers have on them for the connection from it to the computer. You can guess why I didn't use it.
Nice IASIP reference
I had an unpowered USB hub that with nothing plugged into it The computer wouldn't boot and it kept giving an error saying that too much power was being drawn from a USB port.
I'm serious when I say I had nothing plugged into it whatsoever.
What software is being used to investigate the USBs? Not sure if I missed that info, it looks super helpful!
Love this video (and type of video) so much, really pulls you with it and the education to entertainment ratio is, as the full product, Gold!
it's only limited by your BIOS, It's up to be up to the kernel to limit the number of devices in windows, but since windows 10 they removed the limitation. Get an older version of windows like windows 8.1 maybe devices is 128. One of the reasons they remove the limit is because of root kits as you know are drivers…. You got to know windows 10+ is virtualized the whole OS, even tho your not in a virtual machine. The reason for this is because its a security feature built-in windows (cause when someone can plugin a device and overflow your computers drivers and break into your system that is a problem). Since its virtualized you can have as many devices as you wanted. Would be fked if had a machine with 1000s of VM on its and you couldn't talk to the USB controller anymore. Still dont believe me just look taskmgr you will see UAC virtualization, which proves your ur computer is running in a virtual…. I'll leave it at that. Still good video.
Edit:
Also lookup "Windows Defender Application Control and virtualization-based protection of code integrity" and "Windows Defender Application Control (WDAC)" which virtualizes you devices you have. also note that "WDAC has no specific hardware or software requirements."
This was a fair bit boring.
what about the mac
Secretly, this is an ad for AMD.
Now power them up all together and so how the computer handles this!
Again awesome video!
Meanwhile my Anker powered usb controller can’t handle a Mousemat, game pad, keyboard, mouse, headphone wireless adapter, webcam, and a usb microphone.
I can't believe that you didn't try to shake 50 Mice at once and are what happens
This video is way beyond the other videos, congrats Linus this is a great video
This is the stuff I come to LTT for. I have always wondered how many USB devices you can plug in at one time.
Music and hair scream 90s what’s going on here
I forget sometimes Linus isn’t from the us til I hear him say you know lol love it
i did test it, on Thunderbolt 3, i did better then on the newer chips.
you need intel supported devices xH, able to address them all, Logitech G all is, Hubs, only some. Thunderbolt supported hubs !Why power, are they working, after that, do they charge ?
gimme 1 keyboard
Lol Linus face at the 8k theoretical limit 😂
this video is totally useless
I love how Linus just tries things that nobody thought of before and that would never happen like that. Keep it up!
Greetings from Germany 🙂
Uuhhh…. sorry… i just had to unplug your paid advertisement and plug in again after it was over…
There needs to be a sequel! How many thunderbolt devices can you plug in at once
We have a mouse infestation 😅
If you have a mouse infestation, plain old 50 cent mouse traps with peanut butter. Works every time.
Like he didn't know it was a hot mouse
I’ve had issues with plugging in too many hubs rather than too many devices which is interesting. Having the same amount of devices plugged into two hubs seems to work better than having them plugged into 4 different hubs. Also some hubs work almost flawlessly whereas others just keep dropping out when I connect thumb drives to them but peripherals work fine… USB stability, even more than the instantaneous number of devices you can have plugged in, is a big issue and it would be worthwhile to investigate stability in a seperate video. I will say that having a seperate usb controller via pcie definitely improves stability! I’ve noticed that. But when I plug in multiple external hard drives I have significant problems with them just disconnecting intermittently even if they are on seperate controllers (this happens more often under high bandwidth usage but also seems to happen even if I’m just using the drive a little bit??). I’ve noticed this issue on different devices; my old Dell intel 7th gen i7 laptop and on my X99 5820k PC. 4 port powered hubs seem more stable than 7 port powered hubs and 7 is more stable than 13 port hubs; but I have another specific 8 port hub that isn’t sold anymore and for some reason is super stable. Maybe stability varies on vendor or newness of technology like Linus noticed on AMD vs Intel. I wonder if there’s a measurable difference on USB stability and % uptime on Windows vs Mac or from vendor to vendor
Hahaha yep stream deck or GoXLR is always a win
I'm curious how a Linux system would do with the same tests.
so 99 is the limit?
Why can’t you guys just give me some advice?
That Room reference killed me
Try that on a laptop and I will shutdown
"I'm stepping down, I'm also lying."
Meanwhile with a standard mouse, usb light, rgb keyboard, stream deck XL, camlink and a wave 3.. functions fine but when i open discord even if the only thing running i get bandwidth error
is this the same for linux?
