USB 2.0 Coexisting With USB 3.0 Despite USB 3.0 Being Backwards-compatible
-
I've been looking for new hardware to build a mini-ITX server. USB 3.0 support is a must as are SATA 6.0Gb/s, ECC DDR3 RAM, and gigabit Ethernet. Disappointingly, no such motherboard exists with all the features described. Instead, after so much browsing and searching, I've noticed how so much hardware out there are USB 3.0-enabled and curiously, despite USB 3.0 being backwards-compatible with its predecessors I find that computer cases and motherboards will almost always have USB 2.0 ports coexisting with the newer USB 3.0 ports. If USB 3.0 is the new standard and is backwards-compatible, why half-ass the hardware by providing "crippled" ports adjacent to the super speed ones? I'm just curious since I have been coming across computer cases with both USB 3.0 and 2.0 ports.
