Hi Michael. There's really not anything we can do about
this. I would say your laptop is barely sufficient for running Windows 10
at this point, and it may be time to upgrade. There are some things
you can try that might help beyond changing the process
1. Make sure Windows isn't allowed to "manage" the USB
ports as part of a power management scheme.
2. Take a hard look at what else is running on the
system, especially all the background processes. An imaging laptop should
really just be doing things that support that task. Unless you've taken
steps to avoid it, there are often dozens of background processes that are
constantly checking for updates or otherwise getting in the way. Bloated
anti-virus packages are another common source of unwanted
3. Be sure to disable all Windows update activity during
imaging sessions, including just "checking". You can do this in the
Settings/Update area by deferring update activity for whatever period of time
you're comfortable with.
4. If necessary, you can try using sub-frames in PHD2 although
this will prevent the use of multi-star guiding.
You should also investigate whether these problems occur when
there are concurrent image downloads from your main imaging camera and
PHD2. The trouble-shooting section in the manual for "timeouts" covers a
spectrum of things to investigate although it sounds like your problem is
probably with the PC.
Hope you can get it sorted out.
