The USB tether does not work

[fargus111111111]

After almost missing a match because we were waiting for our radio to boot so we could reset some things on the robot we decided that it would be a good idea to investigate the use of the USB tether option with the roborio as the rio boots up significantly faster than the radio. Everything I have found indicates that the rio should just connect as it does over wifi or ethernet, however this is not the case. I cannot ping the roborio over usb nor get any sign that it connected except the tone that sounds when you connect any usb device to the computer. All that said we can connect reliably over ethernet and wifi, for whatever that is worth. Any assistace would be appreciated. The roborio has been imaged recently. We are using a Dell Latitude laptop running Windows 7 32 bit and we do have the most recent update to labview
