Thread: Trouble with cheap serial->usb reader from China.

I purchased one for ~$20 shipped, and naturally it only logs the obdii time and a bunch of empty position values. Any ideas about what I can try to get it working?

Opening serial port /dev/ttyUSB0, this can take a while

Couldn't open gps port on startup.
