Recently purchased ST-i-c, with supplied USB 15ft cable. Installed drivers & updated as per instructions using SBIG 64 bit Driver Checker. Installed CCDOps5. Plugged in ST-i-c via computer USB port. Green light illuminated. Windows (7) says "installing new hardware" then correctly identifies as SBIG USB-64 Camera with Firmware. Then, all attempts to connect to camera fail: Using CCDOps, "Establish COM Link" results in: "No camera could be found.." message. Using SBIG 64 Bit Driver Checker, Firmware tab, "get Firmware version from Camera" results in: "Error: Could not establish a link to the Camera.." Note that I can hear the shutter click once on each attempt to connect. Any ideas? Thanks!
Update: It was the mini USB cable supplied with the camera. Changing to a 6ft cable solved the problem.
Glad you got it working. Probably a voltage drop issue - the ST-I takes almost the maximum current from the USB interface.
