Magnus Bergmark 1387cf623d
The official RTL8192EU linux driver from D-Link Australia 
Version information: 20140812_rtl8192EU_linux_v4.3.1.1_11320
  2014-08-12
  version 4.3.1.1_11320
Source:
  ftp://files.dlink.com.au/products/DWA-131/REV_E/Drivers/DWA-131_Linux_driver_v4.3.1.1.zip

This version does not currently work on newer kernels, but it does
contain USB ID 2001:3319, which a lot of other repos in GitHub does not.
