I have tried every suggestion on this website and many others to no avail. Is it even possible to do android development for a nexus 7 on windows?
I have tried the usb driver downloaded from the sdk manager, the one from asus. I have tried changing the usb mode to PTP and I am still getting the the same message when I try to install the driver (manually).
"Windows could not find driver software for your device"
I know this question has been answered, but I just ran into an issue where uninstalling the Unknown Device, and then updating the driver manually was not working (by selecting the sdk/../usb_drivers folder). No matter what I did from Device Manager, I could not get the drivers to be found/installed.
Hopefully this helps someone - if you have an issue installing the device (Win7), this worked for me:
I just had this problem occur for me with two factory new Nexus devices (Nexus 7 and Nexus 4). For both devices, I had to do the steps above and everything worked fine afterward.
