USB 3.0 device doesnt work but USB 3 shows up

I just bought a usb 3 adapter for my sd card and it is not recognized. (but is on my macbook air) Its strange because i have a usb 2 device( bluetooth adapter) plugged in a usb 3 slot. The usb 3 adapter does not even work in usb 2.

I removed the targus bluetooth adapter from the usb 3 and plugged in the 3.0 adapter and it works fin but only in the one usb 3 doesn't work on the other usb 3 not sure why
