This sounds like a Nebulosity issue.
I use the QHY-8 and Maxim DL for imaging, and PHD and the QHY-5 for guiding, none give me any halts. But i am using "Mount" control and not gpusb. Did you copy the latest CMOSDLL.DLL file into PHD directory ?. It should be on the QHY-5 drivers disk if you havent.
