Thanks, that seems to work somewhat better (patch attached):
umass0: Hitachi, Ltd. DVDCAM USB HS Interface, rev 2.00/1.40, addr 2
da2 at umass-sim0 bus 0 target 0 lun 0
da2: < > Removable Direct Access SCSI-2 device
da2: 1.000MB/s transfers
da2: 1338MB (685296 2048 byte sectors: 255H 63S/T 42C)
However, the device doesn't seem to have a valid partition table:
[root@nik: /] fdisk da2
******* Working on device /dev/da2 *******
parameters extracted from in-core disklabel are:
cylinders=42 heads=255 sectors/track=63 (16065 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=42 heads=255 sectors/track=63 (16065 blks/cyl)
fdisk: invalid fdisk partition table found
fdisk: /boot/mbr: length must be a multiple of sector size
AFAIK the camera should show up as a regular hard disk, even though
internally it uses a DVD file system. Any ideas?
Lars
PS: The attached patch also has an additional usbdevs entry for a
Toshiba e740 PocketPC that I had in my local tree.
