I always thought USB host is a hardware implementation, in the device's chipset. Some devices have USB host, others do not.
Whether USB host can be turned on or off with software or rooting, I don't know. And would there be any need to enable/disable USB host with software?
I've got two 4.0 devices here, a phone and a tablet, plus I've got a USB OTG cable that came with the tablet. I can plug a USB mouse and keyboard into the tablet and they work fine, just like a little PC...LOL. But if I do the same with the phone, absolutely nothing happens whatsoever. AFAIK
the phone just doesn't support USB host, end of.
