Hi everyone,

Recently we purchase a 23UM021 to work under Linux.
We have problems to enable trigger mode, because seems that this camera has no control to enable, rather in the specification say that its capable.
After apply the uvc extensions (downloaded from https://github.com/TheImagingSource/tiscamera/wiki/UVC-Extension-Units) some new controls are accessible, but no trigger one, see this log:

//Upon startup

# v4l2-ctl -d /dev/video1 -l
brightness (int) : min=0 max=4095 step=1 default=16 value=16
gain (int) : min=32 max=2047 step=1 default=32 value=32
exposure_absolute (int) : min=1 max=10000 step=1 default=333 value=10
brightness (int) : min=0 max=4095 step=1 default=16 value=16
gain (int) : min=32 max=2047 step=1 default=32 value=32

# sudo uvcdynctrl -i usb3.xml -d /dev/video1
importing dynamic controls from file usb3.xml.
usb3.xml: error: video1: unable to map 'Auto Shutter' control. ioctl(UVCIOC_CTRL_MAP) failed with return value -1 (error 2: No such file or directory) // a lot of error lines like this ...

# v4l2-ctl -d /dev/video1 -l

roi_auto_center (bool) : default=1 value=1
brightness (int) : min=0 max=4095 step=1 default=16 value=16
gain (int) : min=32 max=2047 step=1 default=32 value=32

any idea?

Jose.

PD:
Perharps is time to open a independent chanel for linux related problems, ┬┐no?

Hello

I am very sorry, but the DFK 23UM021 has no trigger support at all. Even not in Windows.
