Robin,
I'm struggling to see this pause in guiding with PHD. On my mount PHD appears to carry on with 1 sec guide exposures and corrections while the QHY8 downloads (usually takes 5-10 seconds to download an image).
How can you tell that the imaging camera driver is blocking USB coms for the guiding?
If this is what is happening it is strange that the drift continues in a line - ie if the drift is caused by the guider picking up some random hot pixel or another star when it re-aquires wouldn't you expect the drift to be more random?
