It will support some combinations of two EaganMAtrix devices (like EaganMatrix MOdule and Slim Continuum). But some dual combinations are not supports as it confuses the Midi devices (two EaganMatrix modules or an EMM and a ContinuuMini, etc)
I think this may be as good as it can get with the duplicate HC-1 resolution added post Beta 1. A robust solution is likely not possible because there is no way to distinguish these devices: they have no durable unique identifier. The result is probably not too bad, as long as you always keep your devices plugged into the same USB ports. Then the enumeration and order of device enumeration lines up with the order of module loading in Rack, which thankfully Rack retains.
