There is no issue with the HDSP9652 as it has no onboard converters. The problem starts when you use external converters (via adat for example) that are faster then the onboard, which makes their latency less then the reported ones (by the driver) and would result in a negative ping (which cubase does not support).
I am not aware of a hdsp9652 hardware revision that is problematic. I believe that that was with the hdsp cards for the multi and digiface.
