Unable to install the Android USB driver on Windows 7 [closed]

Question

So I want to use my new Nexus 5 for debugging my apps.
I tried to install the Android USB driver via the device manager

But my nexus is listed as portable device and uses the default windows driver.
How can I replace the windows MTP-USB driver with the android driver?

When I click update driver software und select "\sdk\extras\google\usb_driver", it tells me that the driver software is up-to-date.

Edit:
USB Debugging is already activated
Edit 2:
Sorry my fault there are actually two Nexus 5 in my Device Manager. The other one accepted the android driver.

Answer 1

First you'd want to make sure you device is in 'debug mode' or 'usb debugging' - set through development settings in your phone's 'system settings'

then run adb devices from your adt-bundle folder/platform-tools to see if it got your device.

Edit: if it doesn't work try, from your 'drivers' tab- Update Driver -> Browse for driver software on my computer -> Let me pick from a list of device drivers from my computer -> Have Disk -> Navigate to your usb_driver folder

Notice the extra step near the end, you don't submit the folder in the "Browse for driver software on my computer" tab
