MK3190-scanner not capturing & displaying barcodes

Gentlemen,

while working with the demos and samples provided by "EnterpriseBrowser" i discover that the scanner is detecting barcodes but not displaying anything.

in the following demo : Feature Demo - Zebra Technologies TechDocs

it is saying that we must click on enumerate and a list of scanners will be displayed, we can choose from there.

but for me nothing is displayed. the application is not collecting anything.

even with the BarcodeAPI : "Barcode API Tutorial - Zebra Technologies TechDocs " the scanner is detecting but not displaying anything.

 

if i work with DataWedge, everything is normal. same for PHP application through EB, the scanner is working fine, but using the samples provided by the EB website, is not successfully working, as per reading barcodes.

 

any advice regarding that??

 

thank you
