Hi Dan,
   It is not set up at all for audio on the host. I don't intend to use it
in Linux
at all at this time. Line6 doesn't support Linux, they provide no Linux
software and my use on the computer at all, at least initially, is simply
to use the DSP edit control software to create & tweak patches. That will
either be by rebooting this machine into Windows, or solving the
disconnection problems in the Windows VM. However I have found in the
Line6 forums that some people see this disconnection problem even
running in Windows natively so possibly I've just been lucky and now
seen it in the 2 or so hours I forced myself to use Windows to update
the DSP firmware and do an initial checkout of the machine.

   That said the device is a USB audio interface providing 8 USB input
and 8 USB output channels from the DSP + a stereo dry input over
USB. (And possibly more stuff over USB but at this time I haven't
investigated that.) I track, in both Linux and Windows, using Harrison
Mixbus32C (the for pay version of Ardour) and I will certainly be
investigating that at some future date but for now I simply intend to
take the audio output from the DSP to a normal input preamp interface
for recording and not use USB at all

   From the standpoint of the Linux host my preference is that KDE
and most Linux apps don't even know the device is present.

Hope this helps,
Mark
