USB Barcode Scanner not working properly under Windows Virtualbox

[itsbasti]

Environment: Using a Linux host with Virtualbox 5.0.20 and a Windows 7 Prof. guest.

USB 3.0 XHCI activated.

There is a USB Barcode Scanner (Datalogic Powerscan) connected and installed. For some reasons, the scanner is not working proberly. It works correct for 5-10 times of scanning and then it drops a couple of characters out for the next scan. It correctly scans into Linux - without any error.

It must be a reason of the Virtualbox USB Handling.

If i open wireshark with USBPcap installed and start to sniff the USB ports the problem is solved, as long as the Wireshark is running. See attached File for more information of scans.

There are already 2 Tickets of this problem, years ago but without any solution
