OP USB manager tab : USB Manager and Add windows stay empty - Didier B - 2018-01-18
Hello happy OPists !
I have tried many usb peroipheral and wanted to make some housekeeping in the USB and NMEA tabs.
I have suppressed all usb lines from NMEA tab (only left 4 lines unchanged : system_a, system_b, opencpn and signal K.
I have also removed any line in USB Tab. Then rebooted and ran AutoSetup.
Seems it was a mistake, as USB manager is empty, and Add windows is empty too !
Any suggestion ?

I would use the linux command
"lsusb"
or
ls /dev/tty*
to test if linux / raspberry does recognize your devices.
Connect and disconnect a device should show different results.
Openplotter USB Manager does only create one file. You can delete it, if your USB-manager list is empty.
"sudo rm /etc/udev/rules.d/10-openplotter.rules"

Thanks for your answer, which is so useful !
FYI, I tried the lsusb, which showed the connected peripherals OK.
I will keep a note that in case of problem with population of USB tab window I should delete that file.
Btw, what about adding a section "What to do if (or when)..." to the documentation ?
Anyhow, the use of the delete button in the NMEA ans USB tab seems full of danger ...
