USB issues since 4.3.14

[Forage]

Ever since vbox 4.3.14 I've got issues with, what I think is caused by, my USB device. Vbox 4.3.16 didn't make a difference. In both cases I updated the extension pack and guest additions. Both versions forced me to revert to 4.3.12.

Host OS: Ubuntu 14.04 (x64) Guest OS: Windows 8 (x64) Device: Jabra Link 350 USB dongle

Behaviour using this device differs. Sometimes only Lync hangs when I receive a call; when I do manage to call sound it distorded (audio slowed down and choppy); sometimes vbox completely hangs when receiving or trying to call. The only way to get Lync running again is force quitting the application; the only way to get vbox running again is force closing it and restarting.

What can be the cause of the problem? Let me know if you need any more information.

The device in the lsusb log I'm talking about is "Bus 001 Device 008: ID 0b0e:a340 GN Netcom".

Can you please try whether the following test build improves your situation? It contains quite a few fixes for USB: https://www.virtualbox.org/download/testcase/VirtualBox-4.3.17-96390-Linux_amd64.run You have to remove virtualbox (not your VMs) before installing this package. Thanks!

I'm terribly sorry about not coming back to you on this issue. I did not receive an e-mail of you comment at all.

The issue is still present in 4.3.22 so I'm, yet again, reverting back to 4.3.12. I take it that means that there's no point in me trying your 4.3.17 test build any more, is there?

Please let me know if you need any more information.

Please reopen if still relevant with a recent build of VirtualBox.
