Can you repeat your tests?  I never announced the cxusb tree for testing, and you tested an old copy.

There was a bug in that version, the new version is posted now.

After hearing successful test results using changeset 56b3acf44eae , I will ask Mauro to merge it.

Please note:  this was changed to use the DEFAULT xc3028 firmware -- the au-specific firmware should no longer be necessary.

Regards,

Mike
