Thanks for the advice,
i tried "aros 440 live" with sam460ex
actually the problem is the same "death of the device"
or it is recognized but no class.hid is associated for example.
at this point it seems to be UDEV the problem I probably have the parameters are wrong or the USB-audio is not completely disabled on the host.
I had also tested morphos with sam460ex and pegasos2 but the problems are the same,
or it's simply not possible I don't know [ Edited by white 20.09.2021 - 19:01 ]
