问题
Is it possible to enable USB debugging (under settings/applications/development) programmatically from within my app?
I was looking at Permission.WRITE_SETTINGS and
http://developer.android.com/reference/android/provider/Settings.System.html,
but I couldn't find anything appropriate.

You will need root permissions to do so from an app.
That said, it is possible to enable ADB by executing the following terminal commands:
setprop persist.service.adb.enable 1
start adbd
This blog post gives an excellent example of how to execute these commands with escalated permissions through su.

First: Your app must be a system app
This line of code may help:
Settings.Global.putInt(getContentResolver(), Global.ADB_ENABLED, 1);
and you need this permission:
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>
but after adding this permission in manifest you will get this error: Permission is only granted to system apps
which means your app must be a system app.

It's not possible without using your own custom firmware that grants access to the security settings. See thread here: http://groups.google.com/group/android-developers/browse_frm/thread/953c6f0eb0fa9bed#

You can enable adb programmatically by requesting WRITE_SECURE_SETTINGS in manifest and granting it over adb shell:
adb shell pm grant your.package.name android.permission.WRITE_SECURE_SETTINGS
Then you can enable adb on API 17 and above by calling:
Settings.Global.putString(mContext.getContentResolver, Settings.Global.ADB_ENABLED,"1");
For API 16 to API 3 call:
Settings.Secure.putString(mContext.getContentResolver, Settings.Secure.ADB_ENABLED,"1");
To disable adb replace "1" with "0" in commands
