Why does “Unknown device” show in the device manager after connecting the camera?

Applicable Product(s) : For All ASI Cameras

Description: When you use ASI camera for the first time, you may bump into some problems, this post will help you get familiar with your camera ASAP.

What should I prepare?

1. Install ASI Camera drivers : https://astronomy-imaging-camera.com/software/
2. Install latest capture softwares : https://astronomy-imaging-camera.com/software/

Answer:

Because the driver was not installed properly. Try to install the driver again. You may need to stop any anti-virus software to run the installer program.

(NOTE: Make sure you download the driver from the ZWO official web site or from the CD-ROM to prevent any malware problem!)

Please update the driver manually if re-installation doesn’t work.

Right click the “Unknown device”, choose the “Update Driver Software…”option and choose the driver directory. Normally, the driver directory is under:

C:\Program Files (x86)\ZWO Design\ZWO_USB_Cameras_driver\
