For the original porting work done on OpenWRT, check this link: https://wiki.hackerspace.pl/projects:zsun-wifi-card-reader
For more recent work done to get up-to-date LEDE builds running on the device, check https://forum.lede-project.org/t/supporting-zsun-wifi-card-r...
So the state of the art for these devices is a couple of months old LEDE builds.
This seems to be a somewhat rare feature... I might get one just to try this.
Does anyone know of other cards that support something like this? Is there a difference between being able to associate with multiple APs and being able to host multiple APs (or some combination of both)?
I wonder how soon a nice security-oriented package set will emerge. I suppose the USB interface should work as a USB-connected NIC, offering https / ssh / u2f access to the host on the card.
There are loads of devices with tiny WiFi antennae that work fine.
