Hi, I am running FreeBSD 8.1-STABLE amd64 and have got a strange problem when I try to attach and mount my 16 GB USB pen drive.=20 # dmesg=20 delivers something like ugen1.2: <vendor 0x058f> at usbus1 umass0: <vendor 0x058f Spaceloop 16GB, class 0/0, rev 2.00/1.02, addr 2> on usbus1 (probe0:umass-sim0:0:0:0): INQUIRY. CDB: 12 0 0 0 24 0=20 (probe0:umass-sim0:0:0:0): CAM status: SCSI Status Error (probe0:umass-sim0:0:0:0): SCSI status: Check Condition (probe0:umass-sim0:0:0:0): SCSI sense: DATA PROTECT asc:6e,17 (Reserved ASC/ASCQ pair) (probe0:umass-sim0:0:0:0): AutoSense failed No /dev/da0s1 is created and of course it can not be mounted. On the other hand: when I attach the drive and reboot I get: # dmesg ugen1.2: <vendor 0x058f> at usbus1 umass0: <vendor 0x058f Spaceloop 16GB, class 0/0, rev 2.00/1.02, addr 2> on usbus1 Root mount waiting for: usbus1 Trying to mount root from ufs:/dev/ad0s1a (probe0:umass-sim0:0:0:0): TEST UNIT READY. CDB: 0 0 0 0 0 0=20 (probe0:umass-sim0:0:0:0): CAM status: SCSI Status Error (probe0:umass-sim0:0:0:0): SCSI status: Check Condition (probe0:umass-sim0:0:0:0): SCSI sense: UNIT ATTENTION asc:28,0 (Not ready to ready change, medium may have changed) da0 at umass-sim0 bus 0 scbus3 target 0 lun 0 da0: < Spaceloop 16GB 8.07> Removable Direct Access SCSI-2 device=20 da0: 40.000MB/s transfers da0: 16086MB (32945152 512 byte sectors: 255H 63S/T 2050C) GEOM: da0: partition 1 does not start on a track boundary. GEOM: da0: partition 1 does not end on a track boundary. Now I can do # mount_msdosfs /dev/da0s1 /mnt and access the drive. What is going on here? How can I access my drive without rebooting? For a comparision: I have got an old USB pen drive (512 MB) which works without any trouble: # dmesg ugen0.3: <USB> at usbus0 umass0: <USB Solid state disk, class 0/0, rev 1.10/1.00, addr 3> on usbus0 da0 at umass-sim0 bus 0 scbus3 target 0 lun 0 da0: <QDI USBDisk 1.11> Removable Direct Access SCSI-2 device=20 da0: 1.000MB/s transfers da0: 503MB (1031936 512 byte sectors: 64H 32S/T 503C) Sorry to say the 16 GB thing works smoothly with Debian, Fedora and even Windows :(=20 Greetings Peter.
