Question Why do cases still have USB 2.0 ports ?

[box o rocks]

I've always wondered why today's computer cases manufacturers still waste FP space with USB2.0 ports when USB3.0 is backward compatible. Usually at a ratio of 2 x USB2.0 ports to 1 x USB3.0 port at that. Maybe that same question could be asked about the motherboard manufacturers. Although, I have seen where some are starting to eliminate USB2.0 ports on the IO backpane. Is it a cost thing? Just curious...

Since not all people will be buying the latest and greatest. If you look at budget options, you'll see USB2.0 on boards more than USB3.0 ports, you also can't eliminate legacy hardware from the market.

Case makers have also done their research into a particular market to learn what's needed in the market/niche.

USB3 headers are much (3 times) larger and with their leads/traces take a lot of space on MB so there' usually only one of them so case manufacturers see no reason to include more, USB2 is still more than enough fast for most devices except for ones that require more bandwidth. Keyboards and mice for instance. can function just as good even in USB1, Scanners and printers are slower than USB2.

Thannks for the replies. But unless I'm missing something, that still doesn't explain why there aren't at least 2 x FP USB3.0 ports instead of just one. The existing USB3.0 header already allows for the 2nd USB3.0 port. Why just one? Why not 2 x usb3.0 and 1 x USB2.0 instead of the reverse? The 2nd USB3.0 port would still work for legacy devices that are 2.0. The needed traces are already there. It costs no more to utilize the unused wiring from the end of the blue cable to add the 2nd USB3.0 port than to use the wiring from the black USB2.0 cable. Sorry if I'm being dense.

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.

You could just as well ask why some cases still have 5.25in bays for optical drives plus 3.5in bays for floppy drives, but other cases have a wall of pretty fans.

If you want a case with two Type-A USB3 ports and one Type-C port, someone out there will have one for sale.

Get what suits you best.

Vive la difference!
