That did help a little. Inserted that line in 'interfaces' file,
restarted networking and network-manager and now Tomtom is not tried as
a network device.

However, it is still grayed out in virtualbox and the VM doesn't see it
as attached at all. Same behavior whether I have a filter for it in VB's
USB devices filters section.

BTW, I have, since yesterday, virtualization enabled on my machine (amd
machine, it is called AMD-V in it?). Is this necessary?
