Trying to get ST-i working on my Dell 64 bit notebook. Downloaded the latest drivers. Windows 7 Pro. detects the camera and indicates no problems. Plugged in the camera and followed the instructions that came with the Diver Checker exactly. CCDOPS reports " No camera could be found. ............" Graphics/Com is set to USB. Nebulocity, PHD guiding and CCDSoft cannect find the camera either. All works fine on my older 32 bit notebook with the new drivers installed. I'm at a total loss. Any suggestions will be appreciated. I've tried this several times. The drivers are really there. Thanks to all.
