11671,VB 4.1.18 - keyboard and ascii barcode scanner interference,error_401,,"Description of environment: Using a Debian host with VB 4.1.18 and guest Win XP. Attached are a USB keyboard and a USB mouse and a USB barcode scanner in ASCII mode.

Problem:
In Guest as long as i do not touch the keyboard everything is fine. Mouse operation does not interfere. Barcode scanner scans dozens of codes correctly. As soon as i touch the keyboard whatever key (erratically - not every scan) It drops a couple of characters when using the barcode scanner. Seems mostly char number 4 and 5 in the sequence. Error can be reproduced consistently.

Additional troubleshooting info:
Correctly scans into Linux - no faults whatsoever. Using keyboard and scanner concurrently - just works as intended.

Setup:
Host: Debian 7.0 Wheezy
VBox: 4.1.18_Debianr78361
Guest: Win XP SP3
Hardware which causes problem: USB Barcode Scanner Datalogic Gryphon GD4130-BK
USB Keyboard 102/104 keys sg (swiss german)
