I am hoping to get some information as to what might be causing the usb connection to shut down. When the s4i in question is plugged into the usb port (and this is both on the owner's computer and our laptop), the computer does not recognize the connection. On our laptop, as soon as the camera was plugged in our mouse (plugged into the same side USB) stopped working. As soon as the camera was disconnected the mouse started working. As we have an Optio S4 that works fine with the same software and the same usb port and the same cable, it seems to be camera specific. We even tried switching the memory cards and both cards work fine in the S4.
Any help would be very much appreciated
