adb doesn't recognize Samsung Note II and Note 10.1

Is there something special I have to do to get adb to recognize my phone and tablet?

I turned on developer mode, but when I do "adb devices" I still only get the emulator or nothing at all if there's no emulator running.

Thanks!

Why is ADB not detecting my device?

In most cases, ADB cannot recognize your device because the USB debugging option is turned off on the device. Turning this option on can fix the issue for you and this is pretty easy to do. Enabling USB debugging does not do anything on your device.

How do I fix ADB no devices emulators?

Update ADB Interface Driver An outdated ADB interface driver can result in the error - device not found or ADB no devices/emulators found in Windows 11/10. To help you out, it is necessary to install a new version for that driver.

In case you are working under Windows, try to install Samsung USB Driver for Windows .. it should be enough ;-)
