There is a very simple way to get an old DNT DigMicro C11 camera working in Windows 8.1. The company DNT has moved on with a newer products like the “DigiMicro Scale 2.0” link to product page , but stopped support for older products. Unfortunately the newer software does not recognize the old hardware, so i found a way to make this product working on a modern system (W8.1).
In the device manager, the camera hardware id was detected as:
The valid driver for this camera is “SN9C201” from Sonix Inc.
download the driver file (USB20PCCam_5.7.26000.0.exe) from the link below USB20PCCam_5.7.26000.0.exe
To display the image i used the VLC Mediaplayer, available from http://www.videolan.org. Open the player and use the function “CTRL + C” open device. Set the mode to “Direct Show”, device to “USB2.0 PC Camera (SN9C201)” and the audio to “None”, this step is mandatory or it will not work correctly!
