Android tablet and usb AIS

[4kMike]

Hi all!

Android users please:
I have a Trueheading carbon RX Ais that is feeding serial data with USB connection. I checked the data speed etc with a terminal app and fixed Opencpn 5.6.2 android the connection according that. First half an hour it worked like Buick.Ships on the map with data updating.
Later suddently nothing!
Didn't toutch anything.
Now installed everything again, and AIS data is flowing on the terminal app, nothing on opencpn.
serial data window on open cpn shows now only the internal compass flow, not the usb serial..
This would be the lo pwr backup when everything else is soaked.
