I downgraded and have postive results.

Currently installed:

virtualbox 4.2.18-1
virtualbox-guest-iso 4.2.18-1
virtualbox-host-modules 4.2.18-7
linux 3.11.6-1

No USB read/write problems any more. I still get Malformed Packet in
Wireshark, but this seems unrelated.

However now I receive crashes of my VM when attaching/detaching USB
devices to my VM often. Guess I have to live with that.
