Good point. I didn't know that (my BIOSes certainly can't do that). Then I'd be interested how those BIOSes access the umass devices. They certainly don't contain a list of quirks, and I guess they don't try 6-byte commands at all and then fall back to 10-byte. According to Gérard's information, I assume that all USB umass devices are new enough to be able to handle 10-byte commands. USB is certainly newer than the SCSI-2 standard.
