I downloaded Genymotion Android emulators for Oracle VirtualBox (http://www.genymotion.com/) on my Windows 7 PC, created a virtual Jelly Bean with Google Apps device. How do I enable ADB access to it? In system settings/Developer options I already enabled "USB debugging", but typing "adb devices" shows empty list of connected devices. Tried adding a USB port for this VM and rebooting VM, but it does not help.
If you launch the VM with the the launchpad (genymotion binary where you download the VMs) and you set the Android SDK path into the application parameters the connection is automatic and you don't need to run
You can find the information in the Genymotion Docs.
