Do USB hubs cause input delay?
“Does a USB hub add latency?” Yes. That process takes a small, but measurable amount of time; usually a few milliseconds, in a good-quality, standards-compliant hub. Plus, any extra cabling (PC to hub, hub to peripheral) will add a tiny bit of nanosecond scale propagation-delay latency to the connection.
Is it OK to use USB hub?
It’s an unpowered hub, so it might not be ideal if you plan to connect more high-powered devices, but it should be able to handle flash drives, phone or tablet chargers, and external DVD drives, among other things.

Why does my USB hub slow down my computer?
The only reason for the connection to slow down is that one computer wants to communicate with two or more other computers. Returning to the USB Hub, the whole “network” hanging off one port is occupied while one packet of data is in transit.
Does a powered USB hub affect the performance of devices connected?
They must still share the maximum data rate supported by the USB port into which the hub is plugged. A powered USB hub wont affect the performance of the devices connected to it (ie. it wont make them transfer any faster).
