Just for the record, I figured this out. My usb and ac power supplies were not configured in the kernel. This lead to the battery service thinking that the device was not plugged in. This information gets reported to the UsbStorageActivity, which then finishes immediately after starting. Once I set up the ac and usb power supply drivers, it worked as expected.
