i need to figure out how to connect my samsung galaxy s3 to my dell inspiron 17r computer running windows 8.1. the problem i am having is that the galaxy s3 appears to be a usb 2.0 device and the computer seems to only have usb 3.0. i get a message to plug the device into a usb 2.0 port but i am unable to find one on my computer. any help with this matter would be greatly appreciated.
i have a usb 2.0 device but i only have usb 3.0 ports on my computer. how do i use this device with my computer

USB is forwards and backwards compatible. The device and host will negotiate the greatest commonly supported link speed. If you are getting a message telling you to plug it into a USB 2.0 port you can safely ignore it.

You should be able to use a USB 2.0 device in a USB 3.0 slot. You should be able to disregard the message and use your device as normal. What's the exact message you get?
No. Not True.
I have a German 3d scanner from Steinbichler Vision...
MUST be run thru USB 2.0. Absolutly does not work with USB 3.0 System and controller.
Period!
I am positive this is not the only device with this issue guys.
The ONLY solution is to get PCI or PCI X card with true 2.0 ports.
Of course, some USB 2.0 devices will work when plugged into 3.0....but! not all.
Save your sanity and get 2.0 card if you still have issues.

If they don't work, then the manufacturer of either the product or the host controller did not follow the USB specification
Ok....but I am still correct in that not all USB 2.0 devices work on 3.0
still need a USB 2.0 port.
Does not matter what brand PC you have in this case.
I am using a Dell PC, but any mdern PC with only a 3.0 controller will simply not work with my device. Device is over $60k 3d White-light scanner to digitize objects.
Manufacture is world leader in digitizing objects. They know PCs inside and out!
Of course they followed the USB specs. at time of invention and manufacturing the product, BUT USB 3.0 wasn't invented untill recently. Many older devices that require 2.0 will not work.
The End!

my computer keeps giving me a message that my USB2 port had a power surge and stopped working..The 2nd USB2 port works fine as I have a mouse in it (the 1st port has a "!" beside the icon when I go to the control center)..Nothing I plug into the USB3 port works except my external USB3 hard drive..

All of you saying 2.0 will work in 3.0 ports are 100% Wrong. I only have TWO. 2.0 slots. The rest are 3.0, I absolutely HAD to buy a Hub for 2.0 for All my devices.. I have a BRAND NEW Logitech G930 headset that will NOT work in a 3.0 port. Nor will my mouse and keyboard., If I try to use my mouse and keyboard in 3.0 ports they just flat out will not work. Its been very very frustrating since I have 6 usb devices. The headset dongle will act like its getting plugged in and unplugged over and over. Whoever said the manufacturer's arent following USB guidelines or whatever, I dont believe this.
I guess we still dont have an answer.. The best answer to this is.. if it doesnt work then get a hub or an addon 2.0 card.
Since no one actually PROVE 100% that 2.0 devices will work in 3.0 ports.

USB 3.0 host controllers follow the XHCI specification which requires that the host controller be able to interface with USB 1.x devices, USB 2.0 devices, USB 3.x devices, and even future devices. In some earlier XHCI controllers there are minor compatibility issues due to design deficiencies. These can usually be remedied through a firmware update.
Funny that there are still people that think "plug and play" is not going to have glitches and that the "engineers" conform perfectly to the standards they say they're going to conform to. USB is backwards and forwards compatible? LOL to the maximum degree! I agree with everyone who has correctly stated that you absolutely have to use the version of USB port for the device when it was invented. An ancient USB 1.0 scanner is going to crap out and lock up Windows 8 if you hook it into a USB 3.0 port. They don't want you using old equipment, that's why they keep upgrading and purposely introducing "bugs" that cause "non-compliant" devices to not work, and don't give you any old USB ports to use on new devices. It's all a joke anyway, because USB has always been light years behind other port technologies such as Firewire and Thunderbolt. Windows and the PC community are what insist on USB, and they have always been "Plug-and-Pray" since 1995.

Solution: turn off computer and start back up (after installing software for the device). Plug, turn off/restart, and then Play.
Story:
I have an HP pavilion with Windows 8.1 and only usb 3.0 ports (apparently). I plugged an Epson ds-510 into it (loaded software/drivers etc. from CD), and had the error message when trying to scan i.e. when starting the scanning software, that there was no connection to the scanner (despite me plugging the thing in and hearing the telltale ding, etc.). I tried all the usb ports on the machine. Same sound, but no recognized connection to scan. Then I did the troubleshoot and to plug the usb 2.0 into a usb 2.0 port. After searching on the web, and it making sense the 3.0 should be backward compatible but that the error message persisted, I was flummoxed. Even windows diagnosis within my machine when "trouble shooting" the epson ds-510 device said the usb compatibility was the issue. It indicated I had a usb 2.0 device in a usb 3.0 port.
So i did the old "restart" on the computer (shut down and fire back up). Worked like a charm. Now the scan button works on the espson ds-510, and if i start a scan from the software side, i don't get the error message about usb 2.0 and 3.0 anymore.
Yeah, this all took a good hour to figure out.

Slightly old post, but based on the number of issues you have it sounds like you didn't install the motherboard USB3 drivers.
They should be included for Windows 8 but Windows 7 requires you download from the motherboard support site and install them.
