Hi, > I choose usb-scsi because of virtio-scsi, > idVendor is QEMU. > idProduct is "USB Attached SCSI HBA". > I originally named it usb-uas. Is it okay? usb-uas would be better IMHO. "UAS" stays for *U*SB *A*ttached *S*CSI. It isn't the only usb scsi host adapter, the other one is usb-storage. This one speaks the old BOT (*B*ulk *O*nly *T*transport) protocol. The qemu implementation supports a single target with a single lun only. For historical reasons it hides the fact that it is a scsi hba and doesn't let you attach a scsi-* device, instead it wants a drive and creates the scsi-disk by itself. cheers, Gerd -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
