Hi Everybody, After several test with IGEPv2 board (OMAP3) and linux kernel 3.17 and 3.18, the OTG works but, (from my point of view) with an weird behaviour. The OTG like a Host only is activated after load a gadget driver, I mean that, If I plug a USB memory dongle in the OTG port before load a Gadget driver like "g_ether" the dongle is not recognized. After load g_ether driver, the usb dongle is recognized without problems. I miss something in the configuration? It this the normal behaviour?
