First using hardware timestamps was important to rule out any delay from host machine capturing the messages and confirm the device was indeed deviating. Then once the device was patched, confirming it was within spec required hardware timestamps too. I did find that host software timestamps would at times introduce some delays not present on the bus (running in a VM with other tasks so understandable and they looked more like system delays than the periodic ones created by un-patched device). The end result though was a fixed device and happy outcome! John.
