Interesting. To answer your question, I have no idea off the top of my
head. I do have what seems to be a similar camera. It is
Bus 005 Device 006: ID 0979:0371 Jeilin Technology Corp., Ltd
and the rest of the lsusb output looks quite similar. I do not know,
though, if it has any chance of working as a webcam. Somehow, the thought
never occurred to me back when I got the thing. I would have to hunt some
stuff down even to know if it is claimed to work as a webcam.
The packaging that mine came in claims "3-in-1":
digital video camcorder (with microphone)
digital camera
web cam
You did say that it comes up as a different USB device when it is a
webcam? You mean, a different product ID or so?
Yes
Look for this in the original lsusb output I provided
:
Webcam mode:
Bus 003 Device 005: ID 0979:0280 Jeilin Technology Corp., Ltd
Device Descriptor:
Oops, right you are. Blame it on my old eyes. They are the same age as the
rest of me, but sometimes they feel older.
Another thing I could not see in front of me when I looked at my Jeilin
Mass Storage camera, was what is written on it. It says there it is a
Cobra DMC300, and it says
"Digital Video & Camera"
I never paid any attention to that before, because for years my priorities
were still cameras. But now, just in case I have lost the driver CD, I
went out to Google and found what claims to be a driver for it. I hope
that, with such a long idleness just sitting on a back corner of the desk,
the battery has not died in the camera. If I get some time in the next few
days to try to fight Windows, I will make some logs of my own. Then we can
compare notes and see if the two cameras are similar, or not. What I am
hoping for, obviously, is that both cameras are downloading JPEG frames,
and use similar methods to do that. If that is true (we don't know that,
of course) then the only problem I can imagine is that both of them are
reported, even in webcam mode, as Mass Storage Bulk Transport devices. If
so, then the camera(s) would need to be blacklisted by mass-storage when
set up as webcams.
Now that I got the supposed driver, I should go out on the web and get the
supposed manual for my camera. Then perhaps I can know how it is supposed
to be used as a webcam and get the needed sniffs. Meanwhile, I hope that
you will do the same.
