Why do practically all motherboards/laptops still offer USB 2.0 ports?


Recommended Posts

Sure, these days, all motherboard/laptops offer at least 1x USB 3.0 port.

 

However, I've not seen a case yet where all of the ports are USB 3.0. (don't mention specific models etc., I'm sure they exist, I'm just saying a overwhelming amount don't)

 

Is there any reason for this?

 

It surely can't still be cost?

They probably buy the usb ports in bulk from manufacturers or sign contracts that say they will purchase usb ports for 'x' amount of years from manufacturer 'z' for a set price. Basically they predict how long they will use the technology before its upgraded and get good deals from manufacturers who want secure incomes. But then when a new technology comes along they have to use up that stock or continue to purchase that part until contract is up which means it will continue to be in new laptops/motherboards for some time after a new technology has come out.

I think it's costs but also most users don't need USB 3.0 speeds just yet. USB 3.0 is built into my newer Haswell chipset system but yeah it shouldn't be an issue anymore with newer systems. I think most newer laptops only have USB 3.0 ports?

Some of my devices do not work right in usb3 ports.  Its for legacy reasons.

Unfortunately, all low-to-mid priced laptops that I've seen still ship with 1 or 2 USB 3.0 ports along with 1 or 2 USB 2.0 ports.

Being that USB3 is back compatible, who gives a s***? Do you have more than 1 USB3 devices?

Reason why... Keyboards and mouses don't need USB3. They work perfectly fine on USB2

 

I have 2 USB3 ports on the left of my laptop (for externals and flash drives) and 1 USB2 on the right side (for my mouse)

i dont even use my usb3 ports  but ive had some usb2 devices just not work properly on them

 

Untrue, they are back compatible, unless you have a cheapo old one...

USB 3.0 on some PCs do not work on bootup.  I could not get a new Dell Precision T3610 to boot off a USB drive in the USB 3.0 slot.  Had to use 2.0.  And even when I reinstalled windows, 3.0 would not work without the correct drivers.

- 7 and before don't support it natively, 8 does.  Probably the biggest reason.

 

- Most chipsets have a max number of USB3 ports they can support.

 

I've heard some devices can be finicky in a USB3 port, but it depends on the chipset/drivers I think.  I have no experience with that.

You doubt my personal experience?

 

Interesting.  How do you propose to disprove it?

Yet multiple comments here say otherwise.

Show me "multiple comments". Techbeck is saying on boot, not in the system. Prove that.

Yes, I doubt it. The 3.0 standard includes full compatibility with backward type A plugs and receptacles. Meaning, as long as it fits, it works.

 

There can be driver issues, but they are exclusive to the device, and not the standard.

Not always the case.

 

I have a Logitech NX80 that's USB receiver doesn't work in a USB 3.0 port on my Z97 board.

My Corsair H100i via Corsair link will only work with a USB 2.0 port (or header) as well. If I use a working version of Corsair link, it fails to communicate via USB 3.0.

Wow, some of you guys should do a google search and see what should be, isn't always the case.

 

Should be backwards compatible.  Isn't always.

Not counting my own:

The H100i works on USB 3.0. I have it working...

 

Are you both still using Windows 7? That might be the problem right there.

Standard doesn't matter.  Whether it works or not does.  Until everything works, there will be a need for usb 2.0 ports, even if just one.

Show us some proof. The issue is most likely the OS, not the port.

I've no need to prove my experience to you.

 

You are just wanting to fight.

 

I've seen the issue in 7 and 8.

WIndows 8.1 x64, it fails to communicate over USB 3.0. Works without any changes on USB 2.0.

Corsair Link: v2.5.5145

H100i is on 1.07 firmware.

If I use v2.7.5339, it fails to communicate on either interface type.

Motherboard is a Gigabye Z97N-Gaming 5 of F3 firmware.

 

Response back from Corsair was that they only support USB 2.0 for Corsair link and that also they only support the latest release (which ironically doesn't work for my system) as well.

Doesn't exactly answer the question but I personally use USB 2.0 ports before USB 3.0 unless the device is specifically USB 3.0... devices don't always work outside of Windows 7 (which is what I use).
