This looks like fun one, i've got a unit on order from Amazon, should
be arrive in the next week or two...

I've found a possible work-around here:

https://github.com/ev3dev/ev3dev/wiki/USB-Wi-Fi-Dongles

Please give this a try..

sudo modprobe 8188eu
sudo sh -c "echo '2001 331b' > /sys/bus/usb/drivers/r8188eu/new_id"

BTW, your version of u-boot in teh eMMC will cause some other
problems.. It's best to run:

sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100

This will "clear" out the first 100Mb of the eMMC partition, thus
removing the old version of u-boot..

BTW, one side issues we've had with rtl8188eu devices is noise from
the HDMI port, are you currently using the HDMI for anything.. If not
you should add:

disable_uboot_overlay_video=1

to /boot/uEnv.txt and that will disable the hdmi output and one source
of noise that causes some wifi antenna issues.
