I have not made a new premade image with USB ADB, but I have it working. In your current BBBAndroid image, replace your uEnv.txt (/boot partition) with the one I have attached. Replace your two init.genericam33xx*.rc files (/rootfs partition) with the two I have attached. In addition to getting USB ADB up and running, the main .rc file also changes some permissions to make them more relaxed. Now, i2c-tools work without superuser privileges and it "wakes up" all four GPIO banks in case you need to mmap() the GPIO registers.
If you watch the FTDI output from the BBB (when the USB is plugged in at
boot), you'll see something like the following:
[ 5.784087] CAUTION: musb: Babble Interrupt Occurred
[ 5.854604] CAUTION: musb: Babble Interrupt Occurred
[ 6.048723] CAUTION: musb: Babble Interrupt Occurred
[ 6.119724] CAUTION: musb: Babble Interrupt Occurred
[ 6.341756] gadget: high-speed config #1: FunctionFS
On your dev system side, use ADB to list the devices:
$ adb devices
List of devices attached
BBBANDROID device
$ adb logcat
...
