Will a USB HUB affects the input lag of gaming keyboards and mice?

Hello,

 

Good day to everyone, I just want to know if you plug your gaming keyboard, mice, headset to a USB hub will it affect its input lag?

Not in my experience.

If there is any, it's likely imperceptible.

Thanks guys for your opinions.

Its obviously never optimal, as a hub literally just takes the bandwidth of one port and splits it up amongst X number of ports. But unless you were using a USB 3.0 port or slower and were slamming the hub with multiple high speed external devices as well as an exorbitantly high polling rate keyboard and mouse you would struggle to even think you perceived a difference. Even then I don't think it makes any difference, but I simply haven't tested it nor do I have the equipment for it.

 

That's actually a rather good video idea, come to think of it. Test all USB specs from USB 1.0 to 3.1 Gen 2 to see if there is a meaningful difference for peripherals? @LinusTech

Possible, but the real question is will you notice it? and will those few lost ms affect you in any way?

Sorry for the necro, but this youtube video (from an underappreciated channel IMO) covers this topic: https://www.youtube.com/watch?v=nbu3ySrRNVc

 

tl;dw: The answer is no it wont.

 

Even when you plug a USB SSD into a hub with your gaming mouse and do a large file copy with that SSD, the input lag is extremely close to what you would get plugging it directly into a port on the rear of the mobo and pretty much having the USB to itself. There might be a tiny difference but it's probably margin of error and is only 1-2 ms.
