In theory a single hub of USB can support 127 devices. In practice, this will not actually occur. Most computers do not have enough power to drive that many devices. A reasonable number would be about 20.
On a typical setup, only one device can be connected to the ports. However, if you have a special USB port, or a device that will split a USB port, you can connect 2 or more devices.
USB Will allow up to 127 devices per host controller. Usually, a host controller has more than one USB port. The host controller will only allow 127 devices in total (including hubs), so you can not have 127 per port.
