I'll look at non-bulk once we have something useable by common folks and Fedora ships ub, but not before. All my devices use Bulk. But also, UFI has to come first. Only then, perhaps, I'll look at CB and CBI. > Of course the world may yet contain advocates of connecting HDD/FDD as > bInterfaceSubClass = x05 "SFF 8070" = Compaq LS-120 or connecting DVD/CD > as x02 "SFF 8020" = read-only CD. I don't have any plans for 8070 and 8020i. I promise to look at patches if someone submits any. However, in my experience, 8070 devices are fickle. They may be better off left to usb-storage forever, with its richer infrastructure. -- Pete
