Hello,
I am writing to this list because I haven't found anything that helps
me in the 'web' nor in usenet.
First I have to apologize for my bad english and mey bad knowing of
what I'm doing with FreeBSD, I am not a 'hacker' but just a user.

Well my problem is mounting my digital camera. If I remember correctly
I did it with
mount_msdosfs /dev/da0s1 /lumix
I think that was under FreeBSD 6.n
But now, upgraded to 7.2, there ist no /dev/da0.
Attached to an iBook with Mac OS X 10.4 the cards were well mounted as
'disk2s1'.

If I attach the camera to the FreeBSD PC the console gives
[attaching the camera]
| umass0: <Panasonic DMC-FX8, class 0/0, rev 1.10/0.10, addr 4> on

|da0: 1.000MB/s transfers
|da0: 14MB (29121 512 byte sectors: 64H 32S/T 14C)

But there is no /dev/da0
# ls /dev/da*
ls: No match.

If I detach it the console writes
[detaching the camera]
| umass0: at uhub0 port 8 (addr 4) disconnected
|(da0:umass-sim0:0:0:0): lost device
|(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x39, scsi
|status ==
| 0x0
|(da0:umass-sim0:0:0:0): removing device entry
|umass0: detached

I haven't any clue if it's FreeBSD's fault, the camera's or mine.
Is there somone who can give me some hint?

Sabine


Have you tried playing around with camcontrol(8)?

Maybe after you've plugged it in, try:

# camcontrol load 0:0:0

then:

# camcontrol devlist

and then try mounting it if it shows up given the above command.

Sometimes, you have to:

# camcontrol stop 0:0:0
# camcontrol rescan 0:0:0
# camcontrol load 0:0:0

to get it to behave.

Before unplugging it, unmount it and then:

# camcontrol eject 0:0:0


Regards,
