Debugging Android app under VirtualBox

[MastaChau]

My friend has gotten this to work, but unfortunately he is on vacation and I'm trying to get this going. 

I'm running Ubuntu 10.04.4 64 under VirtualBox.  I'm trying to get the MODIO project hosted on github to work on my A13-Olinuxino.  I have the project working fine using an AVD based on my device profile for the A13 board.

When I run adb devices, I get the following list:

List of devices attached
    no permissions
emulator-5554   device

The "no permissions" entry is the A13 board, which I connect to VirtualBox by selecting "USB Developer Android [9999]" from VirtualBox -> Devices -> USB Devices.

I have attempted to make the hardware detectable by creating /etc/udev/rules.d/70-android.rules, adding the line SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1″, MODE="0666″, and then changing the file permissions with sudo chmod a+rx /etc/udev/rules.d/70-android.rules and rebooting.

What else could I be doing wrong here?
