Barcode Scanner Windows SDK c# timeout

hi out there!


we are experiencing the following problem (also in the provided c# sample app):


ds9208 snapi w/o imaging.

we start the c# sample app. discover scanner and test datamatrix-barcodes. everything fine.


we just leave the app running idle (no userinteraction) about 1 hour. as we return, barcodes are not recognised by the software, but scanner does success-beep.


is there any timeout?? any workaround to this appearing "timeout"


so far,

greetings bernhard
