ADB doesn't recognize my device in recovery mode I have an ASUS ZenFone 2. I have tried using ASUS USB drivers and Google Android composite ADB drivers on my computer, but neither recognize the device while it is in recovery mode.

Can anyone help me solve this problem?
Had the same problem, plus the device was shown with a yellow exclamation mark in the device manager but only when in recovery mode.

Solution was to install the Google USB drivers for this device again:


Google and Download "Google USB Driver"
Open device manager
Right click device
Update Driver Software
Select "Browse my Computer ..."
Select "Let me pick ..."
Select "Android Device"
Select "Android ADB interface" ...
