So unless I hear otherwise, I will assume it doesn't need the quirk and it will continue to work fine. The problem is that a lot of these quirks were added with no documentation and a cut/paste of both NO_6_BYTE and NO_SYNCHRONIZE_CACHE quirks even though only one of them was needed. Now that no USB devices should receive a 6 byte command, that only leaves the NO_SYNCHRONIZE_CACHE quirks. I am temporarily disabling them to flush out which ones are REALLY needed. They have been disabled since 2003/07/29 and 2003/08/07 for -current and -stable, respectively. I have had 0 messages saying that anything was broken by this. -Nate
