I *like* the sneak-attack approach of remounting behind Nickel's back!
.
I don't know if there's a way to bypass having top tap the "Connect" button, but if there's isn't, a couple remarks:
We tend to ID the devices the same way as the FW update check, instead of the S/N (c.f.,

https://github.com/NiLuJe/FBInk/blob...id.c#L211-L263).
It might be doable to compute the coordinates of where you need to tap in a more generic manner (since we know the resolution of everything, barring the few sneak pixels behind bezels on the H2O & Aura), and then fake the tap programatically (c.f.,
https://github.com/koreader/koreader...pull/468/files). Take that with a grain of salt, the exact touch 'protocol' has a long history of being weird & messily not quite portable between Kobo models...
