Hello,
I've bought Freematics ONE + and also OBD-II emulator. OBDII emulator works fine but I ONE+ have an issue with serial port. When connected to 3 different types on OS (mac, windows, linux) with 4 different usb cables I cannot see interface. On linux I get:

Looks like USB-> serial converter is dead. Any ideas what to check? Thanks.
