How many devices Android 4.0+ can support connected simultaneously?
As far as I can see, there is no software limitation, and google's page on it says nothing about that (https://support.google.com/nexus/answer/2812516?hl=en&amp;ref_topic=3416342).  However, your phone's hardware may not be able to support that, for instance my Nexus 4 gets very hot with only one computer connected, and it will also be slow as all connections have to be routed using the phones limited processing power.
