I CC'd Elio from Riello. Maybe they have seen this before?
I am not very familiar with the code or the protocol, but a quick look at the driver says that you should be able to see traces of the data by passing "-DDD" to the driver.
If you capture the logs this way, I don't think it needs to be for long - especially because it incorrectly detected the phases during initialization. Please gzip the output before emailing the list. Thanks!
