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.
