Electrónica Problema con el AIS

[gipsy_moth]

Hola.
Te cuento como me va con el udev...

He podido "direccionar" correctamente el AIS a /dev/ais y funciona perfectamente, pero ¿es posible que el GPS USB y la señal NMEA que me viene del Interface Raymarine E85001 apartezcan como el mismo idVendor y el mismo idProduct?

Copio lo que me devuelve dmesg | tail -20 al tener conectado sólo el GPS y sólo la señal NMEA del Interface:

lsusb con el GPS y el interface conectado me devuelve:
