I Enabled USB Debugging on CyanogenMod 11 for LG Optimus L7. The Device is showing in Device Manager.
But, it is not showing in ADB devices list. And there is no notifications for USB debugging.
I find solution for this problem..
Download Google USB Driver. please find your device USB Driver from this link.
Then open devices in windows.
after all this you get your android devices.
Since you're comfortable with using Android Debug Bridge (ADB), you can try the following steps in order:
1) Open a command prompt (Windows) or shell prompt (Linux) at
If your device does not show up, try updating the Android SDK to the latest version and repeat the above steps again.
This has always been a problem. Try this, always works for me.
I'd suggest checking the settings of your device. Just like the usb debugging in Developer settings in stock android. Scroll down to # Superuser on the settings panel and tap. At least on my Sorry Xpendaple Goo running Cyanogenmod 11 rc 1, on the upper right corner there's the icon for the log and three dashes or dots. Tap them dots and select settings. Under Security, tap Superuser permissions and select Apps and ADB. Or Only ADB.
