tl-wr720n since the official firmware only has 4M Flash, the version has been abandoned since 17. I updated 16M Flash and 64M RAM by myself.

I modified the WR710N v2.1 version of the compiled file self-compiled 19 ATH79 support version, other things are normal, but the USB is not properly driven, please, to support AR9331 chip USB driver in ATH79 how to do
