A co-worker picked up a shiny new Hitachi DZ-MV100A camcorder which
records MPEG2 video and JPEG stills onto 8cm DVD-RAM cartridges. It
has a USB interface which can be used to download images and movies
from the DVD-RAM while it is inserted. I've found that despite the
vendor-specific class, it's really a usb-storage device. The following
entry in unusual_devs.h gets it so I can "mount -t udf /dev/scd0" and
view the disk contents:
UNUSUAL_DEV(0x04a4, 0x0004, 0x0001, 0x0001,
"Hitachi",
"DVD-CAM DZ-MV100A Camcorder",
US_SC_SCSI, US_PR_CB, NULL,
US_FL_SINGLE_LUN),
This, however, isn't without it's flaws. I've included a log excerpt of
what the kernel has to say while I'm using the drive (successfully).
If anyone has a guess as to what might get things working even better,
let me know:
