What am I > missing? Not extensive AFAICT ... The scmd/cdb is not available until we call scsi_get_command() in the request function. So you would have to add a field into scsi_request, set it in sg (in both sg.c block/scsi_ioctl.c, test via sd and sg when you are done), and add the field in scsi_cmnd, and set scmd one in scsi_init_cmd_from_req(). But as far as black listing, it does seem like a better solution in that user apps do not need special code. Do the devices that require it (well so far) have useable vendor + model strings or usb id's? -- Patrick Mansfield - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
