Antonio, Well, I have 3 usb hubs, each having 7 possible connections, powered with external adapter (so that all the 21 motes (7x3=21) are detected by the systems), now each of these hubs are connected to three unique USB ports in my system. This is the whole setup.
Previously, when I tried just 10 motes connected in the same way as mentioned above, it worked fine. Any suggestions please!
