this bug has a solution it seems. From the info I see here it feels like
a low hanging fruit.

Potential board specific issues can be followed up on in individual bugs
afterwards. The sooner we land this fix in platform, the sooner we'll
know.

Title:
  ADB requires new userland setup w/ linux-linaro-android 3.0-2011.07

Status in Linaro Android:
  Confirmed

Bug description:
  ADB was reworked in the linux-3.0 kernel, removing the need for device
  specific platform drivers (similar to the change I did in 2.6.39).
  However, for adb to work over USB, some userland commands have to be
  issued at boot:

  Workaround:
  echo 0 > /sys/class/android_usb/android0/enable
  echo adb,acm > /sys/class/android_usb/android0/functions
  echo 2 > /sys/class/android_usb/android0/f_acm/instances
  echo 1 > /sys/class/android_usb/android0/enable

  (The above were found in the commit log here:
  https://review.source.android.com/#/c/23890/ )

  After those commands are issued, I was able to get ADB functioning
  with the android-3.0 kernel.
