@abatex Why are you looking for SR id using VM-list? Use
@johanb7 I had the same problem in the past with FTDI-based USB device. I could see it in Xen host, but not in VM. I've spent many evenings trying to make it visible in VM, but with no luck though.
I don't know why, but seems that some USB devices won't attach to VM.
But it will show next time you go to XOA on new cart. I thought you meant ease way to permanently remove it from sources like described here https://github.com/vatesfr/xen-orchestra/issues/4175#issuecomment-488320434
