Android Question USB debugging : no device seen by B4A

[Chelu]

B4A doesn't see any device to installing file to divice.
I haven't changed the pc.
I have do no changes in the pc, but I've changed the phone.
Before, I had a Nexus 5, and all OK.
Now I've a Meizu m2 note wiht Lollipod, and it goes good but he usb debug.
It works great with B4A Bridge and all SDK are installed. Windows detects the smartphone connected via USB and USB debugging activated. But B4A doesn't see any device.
Any idea?

Open cmd.exe. Go to Android SDK\platform-tools\ and run adb devices. What is the output?

"List of devices attached"

and nothing else
