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.
