I don't have GPSD installed to my knowledge, I may be missing something but I don't have a dedicated GPS
receiver on the laptop
I have my GPS NMEA
data connected to my AIS
receiver (NASA AIS Engine) which then outputs the GPS data together with the received AIS messages at 38400 which I have coming into my serial-USB adapter.
What I have noticed after a little experimentation is that from a fresh system boot dmesg shows a few messages containing-
usb 3-1: ark3116: don't know how to do software
starting minicom shows nothing.
If I unplug the usb-serial adapter then re-insert it dmesg shows:-
[ 404.408202] usb 3-1: USB disconnect, device number 2
[ 404.408803] ark3116 ttyUSB0: ark3116 converter now disconnected from ttyUSB0
[ 404.408905] ark3116 3-1:1.0: device disconnected
[ 407.696147] usb 3-1: new full-speed USB device number 3 using uhci_hcd
[ 407.860576] ark3116 3-1:1.0: ark3116 converter detected
[ 407.871203] usb 3-1: ark3116 using RS232
[ 407.871687] usb 3-1: ark3116 converter now attached to ttyUSB0
Starting minicom again comes up with jibberish (like a binary file).
If I now unplug the USB and re-insert it while minicom is running, then minicom starts reporting valid data.
It seems that each time the usb is unplugged and re-inserted the same thing happens unless minicom is running at the time.
I'm still confused.
