If it was an 8-bit address number, in theory you could have 255 devices hooked up with the usb host.
ethernet networks use 8-bit addresses, and you can have a max of 253 devices connected to one hub (if it had that many sockets) - I assume one is reserved for this 'enumeration', and one is reserved for the hub itself, and one reserved for somthing else...leaving 253
its going off topic slightly I know, but you can't have too much knowledge!
Something I just though of is that in many computers, the USB ports are all connected to the same host, so you could have a maximum of 127 devices in total connected to
all your usb ports, not 127 connected to
each port.
