I see already we connect automagically only with devices that claim compliance to a published standard. Good to hear, thank you. Starting again now: I hear you saying we're talking SCSI to our failing Sony stick only because we patched unusual_devs.h? When we patch unusual_devs.h to say to talk to this Sony stick, how about we simultaneously patch in a flag to say don't talk mode sense to it? As you can see, by now I see only the principle that we can see sd doesn't yet quite Talk Like Windows. I've lost track of why specifically now we believe sd has an issue we should fix. Help?
