[SOLVED] USB manager ver 0.12.0 - JD1 - 2017-07-05
I have two RS422 to USB adapters and a USB GPS puck hooked up to a pi 3.
The USB manager only recognizes two devices in auto setup and doesn't give me the option in 'add' to add the third device. If I delete all devices in the USB manager it then shows me three devices that I can add but as soon as I add one device, I am only allowed one more for a total of two devices.
Under the NMEA0183 tab, when I highlight one of the devices and double click to edit, then go to 'port', one of the available ports is listed twice in the drop down selector.

I have also strange behavior in the USB manager under 0.12.0
Was first suspecting that my powered USB hub has died and used another hub but same behavior: neither on autoconfig nor manually I get USB devises recognized. I suspect that some leftovers from previous USB settings block new reading.
Is there a way to delete all old settings and start new from scratch for the USB and Sensor settings only?

There wasn't any change in USB-manager since month.
I had a situation where rpi does recognize a usb-serial with serial and next time without serial number.
You can try recognize by port for all usb-serial.
If you need more help we need to know what's the result of "lsusb".

I did not try to use the USB manager in earlier versions so I don't know when the issue showed, just that it is there.
Below is my 'lsusb' output. Devices 4, 5 and 6 are my external USB devices.
Looking at this I can guess what the issue is - vendor and product numbers are the same for two of the devices which could easily mess with the works. Is there a work-around if one has two or more of the same device ? Both device 4 and device 5 are NMEA0183 to USB converters. I will try 'by port'.
Thanks !

Yes ! 'by port' works and solves both the issue in the USB manager tab as well as the port selection in the NMEA0183 window!
Thanks!!!!!
