How do USB ports break?
There are small wires inside the cables and they can break if flexed a lot over time. The solution to this is to use a much thicker wire with a stiffer jacket. The problem is that nobody would want to use a USB cable if it wasn’t flexible.
Can you split a USB port on a computer?
To answer your question, yes, it’s safe to add another splitter (which, although an apt description, is traditionally known as a USB hub). In fact, a PC is theoretically capable of accommodating up to 127 USB ports. By “splitting” a USB port, you reduce the power available to the newly added ports.

The USB device may become unresponsive because of a race condition in the Selective Suspend feature. The Selective Suspend feature suspends the USB device to efficiently maintain battery power by enabling the computer to turn off the USB device. However, sometimes this feature may not correctly wake up the USB device.
What happens to USB ports when selective suspend is disabled?
However, be aware that when the Selective Suspend feature is disabled, all USB host controller drivers (and therefore all USB ports and connected USB devices) in the system are affected. Therefore, your computer cannot suspend any USB devices that are connected to it, and the USB devices can continue to use power while connected to the computer.
How can I check if my USB port is working?
In Device Manager, click your computer so that it is highlighted. Click Action, and then click Scan for hardware changes. Check the USB device to see whether it is working. If scanning for hardware changes fixed the problem, you are finished.
