This is really a Raspberry Pi Zero question more than a Jevois question, but I thought I'd ask it here since someone may have come across it already.
I have a python script that sends serial commands to the Jevois cam and gets video and serial responses via the USB connection. It works fine on windows, Ubuntu and on a Raspberry Pi 3B+.
It doesn't work on a Raspberry Pi Zero. It either hangs or crashes when the script writes to the serial port port depending on which device I use.
One possible clue is that dmesg seems to show the Jevois being treated as an SD card.
