I moved the USB cable to another port on my PC, and am now not able to connect to my ST-i camera. PC is Win7, I moved the cable to a port on another USB hub, got the Windows is looking for a driver msg, let it look, came back and got message driver and firmware installed. Tried to connect with PHD2 program (worked fine two days ago), got error 27. Bounced windows, no fix. When Win 7 is coming up it hits the ST-i and exercises its shutter. Moved cable back to original port. Bounced windows. Tried to access with PHD2, same error. Tried to access ST-i with MxmDL, error 27. Hmm. So, what to do? MxmDL is latest version, and drivers were refreshed in the last 2 months. (Tried to update, but internet access is spotty in my observatory.) PS one thing I can think of: my LX200 was not powered on. The ST-i is directly connected to the LX200 in order to guide it. Is this what error 27 means?
