Ubuntu host "OHCI#0: Lagging too far behind..." 100% cpu core load

[ehallq]

I recently upgraded my setup from running Domoticz on RPi2 to a vm on my new server. To use Domoticz to control my lights I have a USB device named rfxtrx433e. This works well, and I didnt have any problems..that was until I watched my cpu load. The vm ran at 100% on 1 core (watching from hostside). I ssh into my vm and "top" reveiled that nothing had a load over 1-5%, so the problem shouldnt be anything on the actual vm. When I deactivated the rfxtrx433e from domoticz i.e. turning off the communication with the usb device, then the load dropped instantly. When I activated the rfx again, it maintain around 12% load for a while, but after getting this message below in the VBox.log once or twice, the cpu load jumped up to 100% again. Any idea to solve this?

00:02:56.660142 OHCI#0: Lagging too far behind, not trying to catch up anymore. Expect glitches with USB devices

I use the latest virtualbox with ubuntu server 14.04 LTS. The cpu is a pentium G3258. The device is hooked up using USB 2.0

I am a member of the vboxusers group. The usb device works without any problem all the time, however the cpu load is 100% on the core the vm runs on, doesnt affect my everyday use, but it generates heat :(

As you can see, there is no problem in the actual vm.
