Under normal circumstances the device management functions should not be used. And even if they don't work, at some point in error handling the scsi layer will invoke the bus_reset handler which doesn't try to use task management functions any more and just resets the device to recover ... Be sure to run the latest bits (greg's usb tree or http://www.kraxel.org/cgit/linux/log/?h=uas), there have been uas fixes recently which are not merged upstream yet. Might also be bugs in the xhci stream handling are tripping you up. cheers, Gerd -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
