Virtualbox issue: Cannot start VM anymore after update

Hello to everybody,

i recently had to move my OMV installation back from USB Stick (SLC) to a normal harddisk. Everything went fine so far and everything was working. Even virtualbox plugin and VM were working.
Since last Sunday i notived that after an update of the system i do have an issue with virtualbox and my VM.
As soon as i'm starting a VM i get this message
########################################################
The device helper structure version has changed.
If you have upgraded VirtualBox recently, please make sure you have terminated all VMs and upgraded any extension packs.
If this error persists, try re-installing VirtualBox. (VERR_PDM_DEVHLPR3_VERSION_MISMATCH)

I purged the virtualbox plugin and did a complete reinstall. I tested Backports Kernel 4.8 and 4.9 but issue remains still.

Does anybody have an idea how to fix or what i could try?

Thx for your reply

I figured out the issue, for whatever reason virtual USB 3.0 and 2.0 settings cause the issue.
Configuring USB to 1.1 in VM solved the issue
