I have a Toshiba AT7C/8GB tablet running Android 4.4.2 with kernel version 3.10.20-g8ccb947. I cannot figured out how to get the device into USB host mode. When I connect a flash drive via an OTG cable, nothing happens. The drive's activity LED does not come on. The OS does not ask me to mount the drive and I don't see it in the file manager. Even when adding a 1000ma power source to the cable, nothing happens. FYI, I know absolutely nothing about Android. I have heard you need a custom kernel/ROM to enable USB host mode, but most of the guides I have come across are for Samsung and HTC phones. Can someone point me in the right direction? I have no clue where to start.
