Since we now have code that should handle the common case of a failure after receiving 6 byte commands, most of them should no longer be necessary. However, the only way to tell if a quirk is really needed is to test the new code with the quirks disabled. You may have a device (USB camera, pen drive, hard drive, ...) that begins to get errors like "BBB bulk-in clear stall failed" or "Synchronize cache failed, status 0x35". If you get these, you can enable previous behavior by adding: options DA_OLD_QUIRKS to your kernel config and recompiling. Once you do this, please send me the output of "camcontrol inquiry da0" so I can re-enable your quirk for good. I'm doing this as soon as possible so the unnecessary quirks can be removed for 5.2. A similar process will take place in 4-stable after 5.2 has been released. Thanks for your patience, Nate
