Use MagciLink to let router visible and WiFi display(chromecast & airplay mirror) over USB network host for RNDIS.
I find a USB-to-HDMI cable MagciLink, which could do mirror display from PC to display device by using USB gadget ether

Is this required, or would "Set root's password to a secure password" be appropriate?

It's not necessary. It's just a accident.
I found MagicLink to use CGI command to get AP info with username(root)&password(root).

This seems very interesting, thanks for sharing it!
Can you stream any content (video and audio) from iOS over AirPlay?

Great thing.

Probably worth mentioning that no all USB to HDMI adapters support mirroring. Some are just for power, so worth checking before buying.

Anyone know if this would work for most USB to HDMI display adapter, or just only work for magiclink?
