Installed updates to nexus 7 to run on 4.4.4 and installed the proper drivers from asus's support. java android teacher had a video on this and followed his steps but still eclipse does not see the nexus and there is only an option for virtual device manager, not just device manager. ran on windows 7 and 8 and mac os. Mac can't find the jre but windows could. solutions?
Try installing the Google USB driver instead of Asus.
Note that the Google USB driver page says:
The Google USB Driver is required for Windows only in order to perform adb debugging with any of the Google Nexus devices. The one exception is the Galaxy Nexus: the driver for Galaxy Nexus is distributed by Samsung (listed as model SCH-I515).
