[Multisync-users] Can cable "other device" refer to a USB interface?

[Jason Grant]

I have a SE K608i and would like to use multisync over USB. 

I note that the connection type "cable" allows specification of "other device".  I'm wondering if it is possible to somehow associate a device file with the relevant [serial] USB interface, and then refer to this device as the "other device" in the multisync UI.  Does this sound plausible, and if so, how would I go about performing the preparatory step of associating the relevant USB interface with a /dev file?

Thanks,

Jason.
