That’s a Lenovo E480. There are two other USB-A and a USB-C and HDMI on the other side, plus you can’t see behind the dongles but there’s an ethernet port on the laptop as well.
I only have two complaints with what I’m looking at. One is there’s probably not enough power for whatever you have connected to all of those USB things. And two, there’s not enough support for the port that you’re plugging this into to resist the weight of all of the dongles, which could damage the motherboard.
Depends. Modern keyboards, mice and controllers use just a few milliamps and the laptop must be able to supply 500 mA. However, just about anything that charges will use the whole 500 mA or even try to negotiate more. There are even non-compliant devices like heating pads that draw 2 A without asking.
The worst one was the pre Raspberry Pi 3 boards. The early ones used an on board Ethernet chip set that was slaved directly to the USB controller. It was USB 2.0 so it could negotiate 100, but really run much less than that.
Then, if you put in a keyboard, mouse, and a USB thumb drive the USB host would multiplex over them and your bandwidth for data transfer would drop precipitously.
I was so happy when they moved to a real Ethernet chip instead of a USB adapter. The new limitation became the microSD… Of course they also introduced the grounding reset issue on the USB port, but just don’t plus or unplug anything and it’d be fine.
Not always. Some laptops use a daughterboard for ports on one side. It might be connected over USB 3.0 and contain one or more USB ports, a SD reader and even audio jack.

What if they’re external drives with their own power supplies? I’ve done things nearly this convoluted, but used self powered devices.
Then you’re just constrained by the data bandwidth
I’m quite familiar with that one.

It’s plugged into the USB port not the motherboard.
The USB port is attached to the motherboard.

And the leg bone connected to the knee bone.
There is a generic leg bone?
duh, do you not know the song? idiot
(I’m kidding) <3
Yup totally it probably just means femur, tibia, or fibula.
Ohh! Now I get why my knees hurt when I stomp my feet!
No that’s because you’re old.
But then shouldn’t it just be my foot that hurts?
What does it have to do with my knee?
It is yet to take an arrow.

What do you think will break first with enough downward force? The port, or the motherboard solder joints holding the weight?
No this is a schooner.
I hope you’re remembered like Ken M. I always find these funny, even when, or perhaps especially when, they don’t land well in the thread.
