Connecting Kemper Profiling Amplifier To VM Aborts the VM

Description
Connecting Kemper Profiling Amplifier (KPA) http://www.kemper-amps.com/ via USB to a virtual machine aborts the VM.
I have tried with both Linux and Windows guests. No problems when connecting KPA to Linux or Windows machine directly.
Nothing is written to VBox.log when KPA is connected to VM. The VM just shuts down and the state in VirtualBox GUI becomes "Aborted".
In the attached VBox.log you can see bootup of Kubuntu 14.04 VM. After the VM had booted up, I connected KPA to it (nothing written to VBox.log at this point).
In the lsusb-kpa.txt you can see the output of command lsusb -v -d 133e:0001

With VirtualBox 5.0.2 and newer Kemper OS (3.1.4) there is no crash anymore.
The previous Kemper OS version was 3.0.2


Here is a bit more info (I'm using Archlinux with systemd):

Backtrace from generated coredump:
I have coredump file available but the FTP server referenced in wiki (https://www.virtualbox.org/wiki/Core_dump) does not work so I was unable to upload the coredump. Please let me know where I can upload the coredump file.
