Running your program under e.g. strace would help identify where it's
going wrong.
Does the right USB device node show up under /dev/bus? Usually it's
made by udev, or devtmpfs. I don't know how android handles that.
If you don't have /dev/bus but you do have devtmpfs in the kernel,
maybe try:
mkdir /dev/bus
mount -t devtmpfs none /dev/bus
mount --bind /dev/bus/bus /dev/bus
