The numbers (first ACB) and also the channel varies from time to time. I couldn't track down the revision yet, checked r295124 and r295131 so far. Just noticed that probing differs between working (294989) and and non-working revisoin (r296074): The latter attaches cd past ada, the former (working) probes cd first. Will see to find out more until next weekend. Any hints welcome. Thanks, -Harry
