Is it one of those ASUS or similar ones? There is a wifi dongle that has drivers for linux, and says on the box linux support, but actually both the kernel and the provided drivers for the chipset are broken, you need to clone the github of the CHIP manufacturer, and compile it. After that, it works.
Highly unlikely. For all intents and purposes it is impossible to create any system, that is anyonymus and trustworthy. And in voting one is exactly as important as the other. If you tried to make electronic voting, keep in mind, that ANY DEVICE in the chain that runs even microcode, or has any form of firmware is suspect. Better cryptography almost makes things worse.
