Zeroborg with Beagle Bone

I've been attempting to connect a beagle bone with a Zeroborg for a while now.

I am using the following settings to try to connect the boards:
ZB = ZeroBorg()
ZB.i2cAddress = 0x48
ZB.busNumber = 0x02
ZB.Init()

I get the following error with that :
Loading ZeroBorg on bus 2, address 48
Missing ZeroBorg at 48
ZeroBorg was not found
Trying bus 1 instead
Loading ZeroBorg on bus 1, address 48
Traceback (most recent call last):
File "test_connection.py", line 9, in
ZB.Init()
File "/home/ubuntu/Project/zeroborgRobot/src/zeroborg_support/src/zeroborg_suprt/zeroborg.py", line 269, in Init
self.Init(False)
File "/home/ubuntu/Project/zeroborgRobot/src/zeroborg_support/src/zeroborg_suprt/zeroborg.py", line 238, in Init
self.bus = smbus.SMBus(self.busNumber)

self.open(bus)
File "/usr/local/lib/python2.7/dist-packages/smbus/smbus.py", line 83, in open
raise IOError(e.errno)
IOError: 2

I also tried just scanning for zeroborgs using:
ScanForZeroBorg()

That gives the following error:
Scanning I▒C bus #2
No ZeroBorg boards found, is bus #2 correct (should be 0 for Rev 1, 1 for Rev 2)

I also probed the I2C lines and the beagle bone seems to be sending read and write query messages.

Let me know if someone has seen a similar problem.
