Why do cases still have USB 2.0 ports?
Why do cases still have USB 2.0 ports?
I've often pondered why computer case makers continue using FP space for USB2.0 ports even though USB3.0 is backward compatible. Typically, they maintain about two USB2.0 ports for every one USB3.0 port. Perhaps the same issue applies to motherboard makers. I've noticed some are removing USB2.0 ports from the back panel, but it seems like a cost-related decision. Just curious...
Because not everyone will purchase the newest technology. When examining budget-friendly choices, you'll notice USB2.0 is more common than USB3.0 ports, and it's also difficult to remove older hardware from the scene. Manufacturers have studied their target markets to understand what's required in that specific area.
USB3 headers are significantly bigger, requiring a lot of space for their leads and traces on MB level, which means only one is typically used. Manufacturers probably have no reason to add more, since USB2 is still sufficient for most devices, except for those needing higher bandwidth. Keyboards and mice, for example, can work just fine with USB1. Scanners and printers tend to run slower than USB2.
Thank you for the responses. However, unless I'm overlooking something, it still doesn't clarify why there aren't at least two FP USB3.0 ports instead of just one. The current USB3.0 header supports both ports. Why only one? Shouldn't we have two USB3.0 ports and one USB2.0 instead of the other way around? The second USB3.0 port would still function with older devices that use USB 2.0. The necessary traces are already present. It doesn't cost more to use the unused wiring from the end of the blue cable to add the second USB3.0 port than to rely on the black USB2.0 cable. Apologies if I'm unclear.

More than likely it's a cost thing, especially if the case manufacturer is kind of high-volume.
In addition, I would bet in a given computer system, USB 2.0 devices that are in active use outnumber USB 3.0 devices. Like for example, these are all the USB widgets connected in my computer at any one time:
Keyboard
Mouse
Bluetooth adapter
External hard drive
Three of these are USB 2.0. Most of the other devices I plug in are also USB 2.0. The number of USB 3.0 devices that isn't some kind of storage drive I have is one. Those storage drives aren't needed all the time and the one device that isn't is my Oculus Quest 2, which I don't even need to use a cable if I don't want to.
It's perfectly reasonable to question why certain designs retain 5.25in bays for optical drives alongside 3.5in bays for floppy drives, while others feature extensive fan arrays. If you're seeking a case with specific features like two Type-A USB3 ports and one Type-C port, there are options available for purchase. Choose what fits your needs.
Vive la difference!
