Re: [libvirt] [PATCH 0/6] add qemu usb-scsi controller support

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
