Just received my OTG cable and Edimax EU-4208 (usb lan cable with ASIX AX88772B chipset) and it does not work OTB.
After flashing the bootloader through ADB mentioned here
I can confirm it does work!
When doing a speedtest through http://speedtest2.nl
and downloading a 1000mb.bin file I get a speed of 8 - 9MB/s.
Multiplied by 8 gives me a nice 70mbit/s, which should be pretty decent for an USB2.0 usb LAN cable.
(I have a 120mbit cable connection)
Only downside I found it does not
add an ethernet option to my Android Settings Menu.
That sucks because I'm not able to set any network settings this way (IP, DNS, Subnet, Gateway etc).
Is there a way to add this? The OTG cable + lan adapter is purely for network testing etc, so setting an IP, DNS etc would be kinda mandatory.
Also a few apps do not work without a wifi connection, for instance: Fing. Is there a way to trick the apps? I already tried an XPosed module called: Hack Connectivity Service without luck...
