RS232 Callback non triggered from USB Barcode Scanner with RS232 driver interface

Hello, 

 

I've got an USB barcode scanner (NLS-HR4280-H5) supplied with a driver for the RS-232 interface.

My problem is that the COM callback with the character event is not triggered.

However, if I use an RS-232 barcode scanner everything works correctly.

 

Does anyone have any idea what could be causing the problem?

 

Thanks

Mattia
