The C920 specs say it's USB 3.0 ready.
I have USB 3.0 ports on my PC. I can't tell any difference plugging my C920 into a USB 3.0 port or a USB 2.0 port.
What does 3.0 "ready" mean?
Thanks for any insight.

Thanks. I kind of suspected that but wanted to know for sure.
edit: In thinking about your answer a little longer, I think a question still lingers.
All USB 3.0 ports are backward compatible with USB 2.0 devices so how is then "USB 3.0 ready" different from any other USB 2 device?

Your Marketing Department knew saying it's "usb 3.0 ready" would make people believe that it will work at the full bandwith of USB 3.0. That's sounds decptive to me. (of course it works with usb 3.0, I'm sure a old usb 1.1 floppy drive from 1998 will still work on a usb 3.0 port)
I want a USB 3.0 Webcam that shoots in what I call "Actual Full HD" and my definition of that is shooting 60FPS at the resolution of 1920x1080 and not see any artifacts, most consumer Cameras lie and say "well, it shoots at 30fps at 1920x1080, but it shoots 60fps at 1280x720".
I'm a videophile, but I don't want to spend around $800 just for the only usb 3.0 webcam that used usb 3.0's bandwidth.
I figured a ultrabook with usb 3.0 and a SSD could be the next form of hacked Videography. (basically like DSLRs)
next time, specify that means it works in USB 3.0, but it's still limmited to USB 2.0 Speed.
Companies that treat the customers like idiots tick me off. (yes, I did make an account here just to say that)

I have a C920 that I am having problems with.
When I connect the camera directly to the USB 3.0 ports on my Lenovo Thinkpad W510 I get periodic freezes of all USB activity which eventually causes the computer to drop the endpoint. When I connect the camera to my USB 3.0 hub (I tried both a SIIG and uSpeed USB 3.0 hub) there are periodic errors which cause the hub to reset, or unexplained random behavior like my mouse shutting down
When I connect the camera directly to the single USB 2.0 port on my laptop, it works fine.

The only thing I can say reference your problem is that I can't tell any difference when my C920 is plugged in to a USB 3.0 or USB 2.0 port.
You may be having some Lenovo related driver issue, or something completely different. In any case, I'd suggest if your 920 works with your USB 2.0 port, use that port to prevent the problems you're having. If you get the webcam working with a USB 3.0 port you won't see any difference in performance.

Logitech, stop lying! This camera has nothing to do with USB3.0. I bought it because I need USB3 support but this is plain 2.0. USB3.0 would mean 10x more bandwidth which can allow less lossy compression and more cameras connected to USB bus. This camera is 2.0 and I cannot use it for robotics project as intended. Stop lying! People loose money and time because of your lies.

Here is a link to the C920 Specs where you can see that the USB protocol this webcam was designed to be used on is 2.0 this doesn't mean that it won't work plugged in a 3.0 port.
The Logitech Webcam C920 is fully supported with USB 3.0 this means that it will work properly and that the quality and speed may be better than in a 2.0 USB port but always within the webcam limitations.
