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
