    Thanks. for answer on this. msg here and hope its running well in a lots of hours, bestgrtz and be safe the Alain. ON7ATV


  • The Pluto is rather power hungry so you have to be super certain about the PSU for the Pi4 (which itself requires a bit of power). Have you tried a USB power monitor dongle to measure the voltage? You can also use a separate USB line to power the Pluto via its second USB socket (from a 5V /1A charger, NOT from another Pi4 port).

    Well like you say, i test here also the pluto sound usb and others via a external 5 volt psu connected on a usb adapter the psu have 3 amps so also the pi4 works on a externel psu thats give a lots of amps at 5 volt,thats not the problem here i take a olther pi3 for see whats happend. and its the same if i do info in the portsdown4 it haves me usb info and say usb cam,usb dongle sound is connected,

    and test my 2 plutos on the system with diffrent fimware in and 2cpus and a bandw too 6 gig.

    Its strange, have no idea whats wrong???? if i connect the plutos in sdr console tey works fine also over the usb ethernet.

    hope to find a solution here hi hi hi hi best grtz the Alain ON7ATV
