I have a (Dell) laptop with 3 USB ports.
There are two USB hubs connected (13 ports each, hubs are powered by external electric source); so in total there are 27 USB ports (13+13+1).
Each port has a 3G modem connected to it (CDMA USB devices).
When I go to My Computer after that - I see 11 connected devices.
When I run my own program that does some work with the modems - it can see 20.
But there are 27.
I don't get it. Why can't I, and how can I, access to all 27 devices?
