This depends on if you use the other ports on your computer to connect devices to also. If you only use the USB port and connect it to USB hub's you can connect up to 126 devices. Without using any USB hubs you will be limited to only one USB device.

∙ 12y agoThe answer provided earlier is incorrect. Technically, you can use upto 127 devices per port, not 500. Albeit, the more devices you use, the slower it gets, but for the most part, you can safely get away with 3 or more devices per port with any modern device(s).

well you can get over a million but if you use the device that you plug in that makes more if not I'm afraid one.
Seeing as how this is probably for the CompTIA A+ cert, I'll give you the answer they want.
Each USB Host controller supports up to 127 USB devices

Unfortunately the biggest limiting factor isn't how many but more concerned with supply. The USB port would need sufficient voltage to be able to power (x) many devices off a standard rail.
