That's wrong!

I tested the Presonus 1818VSL and the Focusrite Scarlett 18i20 and then
decided to buy the Focusrite. However, hardware monitoring of both
audio interfaces is _not_ supported. The devices could be used with
Linux, because they are class compliant. Sure, you could reserve
at least two channels of those interfaces, for making monitor
connections with jack, but you can not assign the channel by the
interfaces hardware mixers. IOW the mixer of the Presonus is _not_
available, _not_ supported by Linux. You do not get latency free
hardware monitoring for each channel, at best for channels that are
routed by default, or if you made a connection with a Mac or Windows PC
and the interface is able to remember it. The OP's Presonus doesn't
provide this feature, but even if an interface does, it doesn't gain
you very much, if the Interface stores the routing done with a Mac or
Windows PC.
