I purchased ASI120MM recently as a guide camera. When I first connect with PhD2 (2.6.5), it recognizes the camera as the resolution populates automatically in the setup wizard. But it fails to create a dark library. My ASI driver version is 3.0.0.4. PhD2 works with my other ASI camera (ASI224MC). Is the camera defective?

Sean Wang – :
Did you try ASCOM mode to connect the camera in PHD. Does there some parameter incorret? I test a ASI120MM，dark library can be created.

“we try ASI120 using USB2 cable plugin USB3 port, and works well. I think maybe you should try another cable.”
And I did it even before your advice but nothing changed.
But since last week everything seems to be ok, using both USB2 cables to USB3 port on both pc’s … so, what the heck did happen ????

Hi Sam.
I have problems in order to connect my USB2 ASI120MM camera to an USB3 port. When I connect an USB 2 Mouse to an USB 3 port the mouse funcions perfectly but it seems the camera driver does not allow the ASI120MM if connected via an USB2 cable to an USB3 port.
This happens on my laptop as my desktop PC and the capture or guiding SW do not see it. Is it possible to redesign the driver to restore the USB compatibility?
Thanks in avance. M.

As I’ve just ordered an ASI1600MM-Cool I have updated the drivers (2.0.1.3) on my imaging laptop (Win 10). However this has stopped my ASI120MM (USB2) guide camera from working with the native support in PHD2. About half the time I cannot connect to the camera and the other half PHD will connect to the camera but complains that it cannot get an image in 30sec. Before the driver update I had no problems.
The camera is showing in device manager and PHD2 can connect and get images from the camera using the latest ASCOM driver (1.0.2.25).
Any ideas why the native support no longer works or how I can fix it?

Sam Wen – :
just upgrade the PHD2 to latest one
