The first Kindle Fire had USB debugging set to go straight out of the box. The new Fire HD has it turned off, so here’s how to enable it.
Unlike the original Kindle Fire, the new HD version doesn’t have USB debugging enabled by default. Because the Kindle Fire HD has a custom “Amazondroid” interface, the option to enable debugging isn’t in the same place as other Android devices. But fear not, I’ll show you where it is and how to turn it on. And hey…it’s a lot easier than building a mosquito flamethrower.
Enable USB Debugging Kindle Fire HD
First swipe from the top of the screen down to display the Notification menu and tap More.
Next, scroll down the Settings menu and Tap the Security category.
Now on the Security screen tap On for the Enable ADB option.
That’s it! USB Debugging is now enabled for the Kindle Fire HD! Connect it to your PC requires a few more steps that I’ll talk about in my next Fire HD segment on connecting the device over ADB.
