appearing on displays and manifesting in distinctive hues typically indicating speed and status. With almost every peripheral nowadays utilizing USB, one may question what the constraints of USB are regarding load capacity. It is known that additional USB cards can be added to increase the number of USB drives accessible, but how many devices can we theoretically connect to a single USB port before it reaches its limit?
Only one USB device can be connected to a USB port at any given moment. To circumvent this limitation, multiple USB hubs will need to be employed and linked together on one USB port. The theoretical maximum for USB is 127 connections on a single host controller. One could then presume that if your machine has 4 USB ports, it should allow you to connect at least 32 devices to each port. However, this is not accurate due to the constraints of the host controller.
There is a restriction on the number of USB hubs that can be connected through a single USB port, as illustrated in a YouTube video by Doctor Shenanigan. After connecting 5 USB hubs to one USB port, he encounters a Windows Explorer error. The error indicates that a USB hub cannot operate if it is linked more than 5 hubs away from the root port.

Each hub that is strung together can be cascaded only up to five levels deep according to the USB protocol specifications. This restriction of five USB hubs remains even with the contemporary USB-C standard. Windows will generate an error when the hub
