I have just bought a new mini PC, it doesn´t have a Intel Processor, is that important?.. also.. someone wrote that the Rane SL1 interface should hava a green light at the back, mine is blue and I haven´t got mine to work yet.. doesn´t the interface and the computer talk with eachother if the light is blue? /TecNic

Intel processor are certainly preferred over AMDs, but that's not to say AMDs won't work (however, there are very real issues with certain AMD processors and are not recommended or supported).

Blue LED= USB connected
Green LED = external power connected
