Hi Eric,

I have written a long reply yesterday, but I don't see it in the thread...
In short :
- "###.###" was for any duration I tried, from 0.000 s to 1200 s, which I was allowed to choose in a drop-down list.
- My laptop has an internal webcam and /dev/video0 and /dev/video1 are already present before I connect my DMK camera.
- After connecting it, /dev/video2 and /dev/video3 are added.
- $ v4l2-ctl -l -d /dev/video2
                    brightness 0x00980900 (int)    : min=0 max=63 step=1 default=0 value=0
                         gamma 0x00980910 (int)    : min=1 max=500 step=1 default=100 value=100
                          gain 0x00980913 (int)    : min=260 max=1023 step=1 default=260 value=260
- $ uvcdynctrl -d /dev/video2 -c
  Listing available controls for device /dev/video2:
  Brightness
  Gamma
  Gain

Not any mention of long exposure possibility. Although the DMK has, it worked with IC Capture (manufacturer software) on a Windows laptop.
