Hi Mirek,

My suspicion remains in the following options:

> # Use this line for a specific camera by serial number, in this case a Flea2 Firewire camera
> epicsEnvSet("CAMERA_ID", "9211601")
> :

> pointGreyConfig("PG1", 18402100, 0x1, 0)

The second arg of pointGreyConfig is Camera ID, The first option is
"epics variable", but the second is you use the hardcode value.

If it is not your case, it is better to check the connection through
the vendor software whether you can connect or not.

Best,
Han
