USB-ATA bridge firmware writers are dyslexic. Film at 11. What I'm saying is that *our* reason for sending out extended inquiry appeared in SBC2 (block limits VPD). So there is no point in asking devices older than that. The fact that this fixes the problem for Tarkan's crappy disk is a (quasi-intentional) side effect. My patch simply tries to be conservative about asking for those pages.
