Hi I thought that USB3 was downward compatable to USB2. I have a Lenova M10 tablet. I could not get it to connect to my windows PC. When I plugged it in, it went into chargeing mode. After being frusteated trying out settings, I pluged it into a USB2 socket. IT WORKED.

Why would it not work in a USB3 socket if it is backward compatable?
 
Solution
Some USB 2.0 cables don't work well on USB 3.0 ports.

For example if I connect my USB 2.0 Flash to the USB 3.0 port it will work, but if I use an old USB cable it will not work.

Moreover, sometime you have to install Lenovo USB drivers on your PC to make them work.
