Also, have you read the instructions in the Wiki? The reason I ask is that you refer to removing the battery as if that is some sort of requirement, but the Wiki instructions I saw didn't say that. Also, in the section saying you did it under Ubuntu, you say that you get the message Suitable USB device not found, waiting. and then ask what you should do then. The Wiki specifically mentions that message and says what you should do then. If you read the instructions, why do you mention that message as if there are no further instructions at that point?
