William, I'm wondering about the physical setup. I looked through the test_hl340.txt and compared it to the example setup sequence at http://owfs.org/index.php?page=startup-ds9097u
The only difference is one episode on line 53 where your adapter responds 'CF' rather than 'CD' After some sleuthing, that's a "no presence pulse" response to a reset, and is inconsistent in your startup sequence. (The adapter responds 'CD' in other places). Could the line be noisy? I know you said that it worked with earlier versions, is everything the same? Another thought it to add --serial_regulartime to the command line to see if the slightly different timing will help.
