[Noisebridge-discuss] hacking digital camera/binocular combo

[jim]

   Thanks T and Jof. I'll try T's suggestion. 

   Currently: 
   i diff'd copies of /var/log/dmesg with and without 
the camera attached at boot time and there's no diff; 
i inspected /var/log/dmesg "manually" and could find 
nothing; grepping the dmesg files for usb yielded 
nothing; running lshal and lsmod and lsusb yielded 
nothing, where "nothing" means nothing that seemed of 
the camera, at least nothing i noticed. 
   oddly, the camera "sees" the computer: if  <---- 
connected, it stays on; if unconnected it turns 
itself off. 
   seems i'm not noticing something that is there in 
the files and command reports, but this is after 
repeated inspections, so i have given up temporarily 
and plan to do it again with a different, hopefully 
clearer, brain. 
   the thing was made in china, comes with arcsoft 
software, was branded by sharper image and i think 
some others. 
   i've been hoping to save the images, but the 
batteries are getting low and the instructions say to 
get the images off before changing batteries; i may 
try to alligator-clip to an outside set of batteries 
and hope i can then swap new batteries without losing 
power (and images). 
   if anyone's interested, i can bring it in (i'd 
like that).

If lsusb doesn't show any devices, I'd suspect the cable or device
itself. It should at least show up as an addressable endpoint even if
no driver has claimed the device.

Does dmesg list anything when it's attached?
