You're talking about a "modem" here. Depending on the access port on the
other side, the PPP implementation specifics and some more parameters
this will stop working if there is more than a little bit of variance in
packet delays. This probably won't matter if the IP connection is fast
enough (e. g. VMs in Qubes) but I've seen this not working with PCMCIA
modems in PCMCIA-to-USB already (because they were not stable enough to
stay isosynchronous "enough") so don't expect it always to work. This
will get worse if there is some real USB involved.

Considering the "reduced security": We're already afraid that the
controller of a wireless NIC could be subverted at the network control
plane and used against bugs in the USB hardware driver in our USB
controllers. Yet there seem to be people willing to risk connecting
known-to-be remotely controllable wireless hardware (and we're not
talking of OTA updates we're used to get pushed into our "baseband
hardware" if we want it or not) to the system buses of their computers.
It's a bit mind boggling for me. You don't have to be rich to get one of
the gl-inet routers and move your long-range wireless stuff away from
your computer. Or run Windows instead and have all the comforts of a
modern (but a bit snoopy) OS.

USBIP / Xen USB passthrough.

It ought to be possible, at a cost of reduced security, to pass through
individual devices from the dom0 to the NetVM, where they should appear
as regular USB devices that you can just use.

It also ought to be possible to use USBIP to pass through individual
devices from the USB VM (if you are using one) to the NetVM, where
(again) they should appear as regular USB devices.

I have not tried these things, I must say.

Is there no software route i can take? Is is not possible to virtualize a 
specific device and then attach that to the VM or something alike?

I could just get 2 PS/2 adaptors for my keyboard and mouse and set up a 
dedicated USBVM then proxy my 3g modem device to sys-net.
