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?

check that you don't need to update the USB drivers.

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. :pt1cable:

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!
