VirtualBox locks up with USB headset attached

[b-glawe]

This problem exists since the update to VirtualBox 4.3.14.

I have a MacBook Pro with Mac OS X 10.9.4, VirtualBox 4.3.14 (64 Bit), running a Scientifix Linux 6.5 32 Bit (binary compatible to Red Hat Enterprise Linux 6.5 32 Bit)

Inside the VM I run a Teamspeak 2 client for Linux (problem also occurs with other audio software, like e.g. audacity).

I plug in a Logitech headset and I forward the headset to guest machine automatically in the USB filtering settings.

The headset registers successfully and can occasionally be used. However:

My Teamspeak partner complain about very bad audio quality (may this is worth mentioning) and after a few moments (not predictable), all running programs, that have an audio device open lock up. After a few seconds, the whole machine locks. If I'm fast I can submit a shutdown command for the linux guest. It will however lock up with the attempt to shut down the Virtual Box Guest Addistions.

I checked the microphone on a desktop machine (Fedora 20 Linux), where it works perfectly.

The Linux guest is stable like a rock as long as I don't plug in the USB Headset.

I also copied the VM to my Fedora 64 Bit Desktop to run it there (also VirtualBox 4.3.14), which however also fails with the same symptoms.

Thanks in advance...

I should also mention, that the locked up machine cannot be terminated with the common tools, like "Shutdown by ACPI", or "Shutdown", etc. I have to "immediately" (something like "kill -9") kill almost all processes related to with VirtualBox, before I can restart VirtualBox again.

Please reopen if still relevant with a recent VirtualBox release.
