I am trying to set up a serial port emulation over USB on BBB. On my system I have ubuntu installed with an RCN kernel (tired 3.13.11 as well as 3.15.10). The g_serial module loads just fine, creates /dev/ttyG0. The problem is on the other side, when I plug in the USB cable into my linux box, lsusb does not show BBB as a serial device, in fact it doesnt show it at all. There is no device discovery notification. I've tried to boot into Windows as well, same problem - the machine does not detect the USB connection. I can power my BBB over this same cable with no issues (I do however have a separate 5v power supply connected most of the time, as I have a 7" LCD connected). Any ideas would be appreciated.
