I have now Z9X only , but there are 4USB s - 2 of them are 3.0 and the other 2 are 2.0 . Dont know why , but on the PRO they put only 1 USB 3.0 and from the side 2 USBs 2.0 . Mainly i use zidoo with those 2 - 3.0 usbs cause iam play my 4K content from my HDDs . Why do ZIDOO do this , going backwards to the old 2.0 ? Or is it enough compatible to get through the 2.0 4K content ?
