Send mail to mime@docserver.cac.washington.edu for more info. --0-1992410604-1059098409=:42898 Content-Type: TEXT/PLAIN; charset=US-ASCII Attached is a patch that disables ever sending 6 byte commands to buses that do not support them. Numerous USB devices hang when receiving a 6 byte command. For testing, this patch comments out the scsi_da quirks for devices that I believe are addressed by this patch and no longer need the quirk. Please test devices such as USB keys, USB cameras, Firewire hard disks, and ATAPICAM cd drives to be sure they still work with this patch. Especially if you've needed a quirk before, it is important to see if this patch does not break your device. I hope to get this into the tree early so there is plenty of testing before 5.2.
