Hello,

I'm currently setting up a system that uses a PrincetonImaging PIXIS camera. 
As these cameras use an USB interface I have to use the latest version of the 
PICAM library (5.1.2) from Princeton.
With this library the driver connects at startup but looses the camera during 
the initialization phase. In the hardware setup routine the driver registers a 
callback function for the PICAM_Discovery mechanism. This function seems to 
loos the communication over USB with the connected camera if another thread 
talks to the camera.
Has anybody else observed this behavior? I could get around this problem if I 
comment out the calls to the PICAM_AdvancedRegisterForDiscovery function.
But then the driver is only able to use the first detected camera. If I would 
connect two, I can not select the one I want to use.

Regards

Jörn
