Scanner sends keystrokes strangely after opening and closing soft keyboard on TC70.

We are developing a warehouse system and trying to support as many units as possible. We want our customers to use the latest versions of firmware, including Chrome as that is a system requirement from us. In the latest release of our software we have had trouble with the TC70s. We have customers that uses TC75, which works fine. The problem is, when opening the kiosk-chrome-app, we can scan fine, using keystroke as output. When I look in the logcat-log, the android system does a doInject after each char in the barcode(as a keystroke).
