Excuse this if you are seeing this again, I sent it once but I never saw it posted to the reflector. Could be me or T13, not sure....anyway, I will repost. > Why is this discussion needed?

I don't have my notes on it since I left my notebooks at my previous employer. My memory is some of the device manufacturers handled "Set Max" type commands differently and also interpreted the spec a differently on the contents of the mentioned bits and words in ID Device. The company I worked for at the time was developing some drivers and was seeing inconsistencies. I talked with others at one of the T13 meetings and found they were seeing similar things. Anyway, may be a moot issue today. I know it was enough at the time that it did make mention in the document and section (e03107r0 sec. 3.1) I referred to in my previous post. Maybe Mukesh remembers or can answer whether or not it is still an outstanding issue. I believe he picked up the PARTIES-2 after myself and Ron Salmon left.
