    Ok Jan, no worries. Just let me know when we can try again. TV is my preference.

    Hi Colin.
    All seems clear now to give you access to my remote PC to check out the STT-8300WSG camera driver.
    Please let me know when it would be convenient to you.
    Thanks

    Perhaps we could try tomorrow. Am overloaded today. Let me know what time it would get dark.

    Doesn't need to be dark Colin. We can take dark frames, light frames or any image without moving the mount. All I need is to get the camera connected and take one image of anything. The current issue is that the camera has been working but will not download the image. I'm about to get to my bed now but I'll try a connection and take an image if I can connect. If it connects I can guarantee that an image download will fail.
    As I reported earlier in the ticket, I am on UTC+1, ie British Summer Time. 5 hour time difference.
    Tomorrow I can make it any time to suit you but I can offer a starter of 2 pm BST. Is if not convenient let me know the best time for you.
    I am going to try to get a support guy on-site and we can try a 3-way TV session. I am not confident the connection will be reliable but we'll give it a go.
    Just tried to connect to TV - no way!!
    I can connect with Splashtop no problem
    Please do nothing until I get back to you...
    Thanks

    Yes. When you are all powered up and ready to go, send a Private Message with the ID / PWD.

    We're not done yet !
    There was no fault with the SBIG camera, but two things:
    1. Your guy Colin will change the USB power device supplying power to the USB switchable hub to eliminate the USB Unknown device error. I believe he will do this now.
    2. For the COM3: and COM4: devices, you guys need to turn OFF (uncheck) [] Serial enumeration. This will prevent problems with Microsoft assigning a Serial mouse to where the focusers are attached, and that would cause all kinds of trouble.

    If you run into future troubles with performance, I would put the SBIG camera on its own USB2.0 connection straight to the back of the computer. The SBIGs tend to download faster than the Moravians, and if you are running multiple cameras simultaneously (and have the SX CCD in there too), USB performance can suffer/become unreliable.

    Here's a screen shot of what you need to check for each COMx: serial port device on your machine.
    Start windows Device Manager
    Ports
    for each USB Serial Port (COM1 through COM7 or however many you have)
    Right click.... Properties.
    If there is an Advanced button, click that.
    Then check if you have these settings.

    These only apply to FTDIchip based devices, not Keyspan or others.
    The essentials are that Selective Suspend must be OFF (unchecked), and Serial Enumeration must be OFF (unchecked).

    OK Colin. Done all of these.
    I'm very pleased with your findings and very impressed with your expertise.
    Thanks for your patience - I'm delighted to have my favorite camera back in action even though it turned out not to be a camera fault.
    Best wishes
