When connected over USB to a computer, the camera operates as a USB mass storage device allowing access to the MSDOS filesystem (containing pictures) on the camera's internal SDHC/SDXC card. This works correctly when connecting the camera to my FreeBSD8.1 i386 box over USB1.0. The following messages appear in dmesg on the 8.1 machine: =====START 8.1 messages=========================== ugen0.2: <Panasonic> at usbus0 umass0: <Panasonic DMC-LX7, class 0/0, rev 2.00/1.00, addr 2> on usbus0 umass0: SCSI over Bulk-Only; quirks = 0x0000 umass0:2:0:-1: Attached to scbus2 (probe0:umass-sim0:0:0:0): TEST UNIT READY.

GEOM: da0: partition 1 does not end on a track boundary. ========================END 8.1 messages=========================== The camera also appears as expected in /dev (although the name shows up twice -- something I can't ever recall seeing before): ls -l /dev/da* crw-rw---- 1 root wheel 0, 128 Jun 29 23:46 /dev/da0 crw-rw---- 1 root wheel 0, 129 Jun 29 23:46 /dev/da0s1 crw-rw---- 1 root wheel 0, 129 Jun 29 23:46 /dev/da0s1 However, when connecting the same camera over USB2.0 with the same cable to my 9.1 AMD64 box, mass storage mode does not work, and the following messages show up in dmesg: ======================Start 9.1 messages============================ ugen1.3: <Panasonic> at usbus1 umass2: <Panasonic DMC-LX7, class 0/0, rev 2.00/1.00, addr 3> on usbus1 umass2: SCSI over Bulk-Only; quirks = 0x4000 umass2:7:2:-1: Attached to scbus7 (probe0:umass-sim2:2:0:0): REPORT LUNS.

(I don't know whether 9.1 on i386 works with it or not). >Fix: No fix. The only workaround is to take the SDXC card out of the camera and connect to it with a card reader. I don't like doing this because I figure the card connectors are more delicate than the camera USB connector. >Release-Note: >Audit-Trail: >Unformatted:
