That would cut back a bunch on the quirk table, and especially on the need to figure out a device-id and recompile the kernel each time you try something new... (or arbitrarily set the appropriate flag on any device when a 6-byte read or a sync_cache gives a command error, then retry). It isn't clear from /var/log/messages just what error is reported for this case; full sense isn't in the "read" log message, only a timeout. (sync-cache is clearer...) The device works fine with my suggested diff (except that it single-threads rather badly, but one can live with that). Cool having a 128mb USB "disk" that isn't much bigger than the plug. -- Pete--tsRVFpaPf0z4x49Ap2Y1SNGZxTn9501ayRK6OJ060CxKkNJr Content-Type: text/plain; name="file.diff" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="file.diff" *** scsi_da.c.orig Fri Feb 22 18:37:02 2002 --- scsi_da.c Wed Mar 27 16:57:00 2002 *************** *** 317,322 **** --- 317,329 ---- {T_DIRECT, SIP_MEDIA_REMOVABLE, "NO BRAND", "PEN DRIVE", "*"}, /*quirks*/ DA_Q_NO_6_BYTE|DA_Q_NO_SYNC_CACHE }, + { + /* + * Pen Drive + */ + {T_DIRECT, SIP_MEDIA_REMOVABLE, "", "USB DISK", "*"}, + /*quirks*/ DA_Q_NO_6_BYTE|DA_Q_NO_SYNC_CACHE + }, { /* * FujiFilm Camera How-To-Repeat: Buy a Pen Drive (www.pendrive.com).
