FC3 Timeout on ep0in

Just upgraded to FC3 from FC2.  Tungsten hotsync worked flawlessly with Evolution 1.4 in FC2.  In FC3, Evo 2.0, sync starts normally but fails with "gpilotd timeout on ep0in".  Duplicate entries written to Contacts in spite of sync failure.  Googled and searched archives as well as bugzilla and found lots of issues, no solutions or workarounds.  Tried old FC2 kernel, same result.  Any thoughts much appreciated.
