Specs: Windows 7
My laptop troubleshooter says " USB Composite Device cannot work properly with USB 3.0." What does this mean and how do I fix it?

Did it previously work OK on that system? Did you just upgrade to windows 8 or 10? If so check for possible driver updates.

Apparently USB 3.0 doesn't like some devices designed for USB 2.0. The easiest fix would be to use a 2.0 port, if your computer has those too.

This says using a 2.0 cable in the 3.0 port will allow the device to work:

I've changed nothing. I have a toshiba satellite with windows 10 and the printer worked fine until last week.

✔ Best Answer
If nothing has changed since the printer worked then possibly one of the automatic updates has caused the problem. Complaints about problems caused by windows 10 updates aren't uncommon. You might try a system restore back to the most recent date when it worked.

Also, can you try the printer on another computer just to rule out it being a problem with the printer and not the computer or windows?

Other than that, you can try the suggestions in my # 1 above.
