Hi all, So many questions... I can mount/access (mount -t msdos /dev/da0s1 /mnt) my 'Apacer 16MB HandySteno 1.1' USB memory key stick as long as it's connected when I power up my FreeBSD 4.8 server. It does give an error msg on the console saying: (da0:umass-sim0:0:0): READ(6)/WRITE(6) not supported, increasing minimum_cmd_size to 10. I take it that it has done the increasing by it's self using the Apacer quirk in /usr/src/sys/cam/scsi/scsi_da.c I found a bit of info on this at: http://www.root.org/~nate/freebsd/quirks.html but it neglects to say how to recompile scsi_da after it has been edited. It also doesn't go into much detail on how to get the info needed to add a quirk. 'camcontrol devlist -v' reports: # camcontrol devlist -v scbus0 on umass-sim0 bus 0: < USB DISK 2.08> at scbus0 target 0 lun 0 (da0) scbus-1 on xpt0 bus 0: < > at scbus-1 target -1 lun -1 (xpt0) If I unmount it (umount /mnt), disconnect it, and later remount it I get: umass0: detached umass0: USB Disk, rev 1.10/1.00, addr 2 da0 at umass-sim0 bus 0 target 0 lun 0 da0: < USB DISK 2.08> Removable Direct Access SCSI-0 device da0: 650KB/s transfers da0: 15MB (32000 512 byte sectors: 64H 32S/T 15C) umass0: BBB reset failed, TIMEOUT umass0: BBB bulk-in clear stall failed, TIMEOUT umass0: BBB bulk-out clear stall failed, TIMEOUT umass0: BBB reset failed, TIMEOUT umass0: BBB bulk-in clear stall failed, TIMEOUT umass0: BBB bulk-out clear stall failed, TIMEOUT umass0: BBB reset failed, TIMEOUT umass0: BBB bulk-in clear stall failed, TIMEOUT umass0: BBB bulk-out clear stall failed, TIMEOUT umass0: BBB reset failed, TIMEOUT umass0: BBB bulk-in clear stall failed, TIMEOUT umass0: BBB bulk-out clear stall failed, TIMEOUT umass0: BBB reset failed, TIMEOUT umass0: BBB bulk-in clear stall failed, TIMEOUT umass0: BBB bulk-out clear stall failed, TIMEOUT da0: reading primary partition table: error reading fsbn 0 umass0: BBB reset failed, TIMEOUT umass0: BBB bulk-in clear stall failed, TIMEOUT umass0: BBB bulk-out clear stall failed, TIMEOUT (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 ....etc it's then lost, until I next reboot the PC. Qu: is my Apacer device the same one that is mentioned in the scsi_da.c quirk i.e., {T_DIRECT, SIP_MEDIA_REMOVABLE, "Apacer", "HandyDrive", "*"}, /*quirks*/ DA_Q_NO_6_BYTE|DA_Q_NO_SYNC_CACHE Qu: Do I need another quirk added to the above Apacer quirk, or a whole new quirk, as I have a Apacer Handy Steno, not a HandyDrive? Qu: Since 'camcontrol devlist -v' reports that my USB device as a '< USB DISK 2.08>' do I need to set that name up as a quirk instead? Qu: If I do need to edit/create a new quirk, what method do I use to compile the file etc? NOTE: *Any* info I appear to be lacking would be appreciated! :-) Cheers, Paul Hamilton
