Talk like Windows means say -x "12 0 0 0 24 0" -i x24 // op x12 Inquiry for 36, nothing else, at least until broken 64-bit motherboards force us to x20 or x28. > Why can't usb storage conditionally modify the > INQUIRY to request no more than 36 bytes > (allocation length), and modify any results to be > <= 36 (additional length)? sd.c isn't the only client of usb storage. In particular, we need to hold on to some way of letting sg pass thru op x12 Inquiry arbitrary enough to copy In the vendor-specific data out past 36 bytes. Or to copy In the Ans-specified data out there that lets an SFF/ ANSI MMC compliant device report an attempt to comply simultaneously with the somewhat contradictory ANSI SPC. No?
