I am at my wits end.

Last night as I was trying to set polar align using PHD, the camera stopped working.

PHD gives a message after the timeout period of 15s: 'camera failed to respond...'

What I have checked so far:

I connected the camera directly to the Laptop USB 3 port with a short and different lead.
No Change.

I reinstalled the ZWO Windows driver.
No change

I temporarily connected the main imaging camera to PHD.
It worked.
That rules out a lot of things like PHD software, Windows driver, Firewall, Anti virus.

I checked the port in Device Manager.
All fine there.

I connected the ASI 120 Guide to my old Windows 7 laptop.
It works!
That rules out the camera being faulty (I think).


I have nothing left to try.
