DS always disabled

[intellec7]

We can never get our Driver Station out of the disabled mode.

Here is our setup:

Driver Station (eth1) connected to cRIO via crossover cable.
The driver station has software 2008_10_29a (most recent from WPIlib site).
The cRio has image 2009 v7 (most recent).
USB port 1 and 2 are connected to the kit joysticks
The competition dongle is connected in the enabled (down) position.
The DS is in tele-operated mode.

We turn on the DS and wait for it to boot. The screen indicates "Battery: N/A".
We turn on the cRIO. The DS briefly displays "Battery: No Code" then "Battery: 00.00V".

We connect the jumper in analog bumper 1, but even when we do this value is inaccurate, jumping around in the sub-1 volt range) We don't care about this issue too much at the moment, though it might be a related symptom.

The DS displays "Mode:disabled" and we are not able to get it to be enabled.

We have successfully built the sample code and we can upload it to the cRIO without any chance in symptoms.

The IPs of both the DS and the cRIO are verified to be correct. Our DS has the team number correct as well. There is indeed some communication going on as evident by the battery voltage status and ethernet activity.

I have looked throughout the forum and have not found problems relating to "stuck in disabled mode". We have had problems with this DS before (bum flash update). We sent it in and they told us there was a cold solder joint. They fixed it and gave us the board back, but we are suspecting that there might be something else wrong with it. Before going down that path, I'd like to make sure that we aren't missing anything.

(I don't have the equipment in front of me, so my display messages might not be 100% accurate)

Thank you very much.
