I run the command "adb devices" and it doesn't list the nexus 7 device even though the drivers are installed correctly. The drivers show up as "Android Composite ADB Interface". I have "USB Debugging" turned on in the nexus 7 device. Also, I did already try to kill and restart the adb service without any luck.
When I connect my HTC One android device, however, it shows up when I run the command "adb devices" even if I don't have USB Debugging turned on. The main difference in drivers is that the HTC One driver shows up as "Android ADB Interface" when I plug it in. So, it doesn't have the "Composite" in the name.
Any advice on getting the Nexus 7 to show up when I run "adb devices" would be much appreciated!
Try this, connect the device, then swipe down your notifications on the status bar (left side), tap on Connected as a media device
and change that to Camera (PTP)
