Try running a calibration. This is done thorugh ScanGear in Advanced mode. Once in Advanced Mode, in the Image Settings section there should be an option for Calibration (you may have to scroll down in this section to see it). After running the calibration, try performing a preview scan with nothing on the scanner glass. If the red line shows up on the preview now, then most likely the scanner needs to be serviced.

Your connections sound confusing, but you are correct about connectivity being your problem. The more wire and connections between any device and your computer, the worse the results. I have few devices requiring a firewire. Scanners have to transfer a lot of data very quickly. Printers too but they will usually function, just slowly. Your best bet is to simplify it somehow. A long time ago firewires were going to be the big thing by 2000. It never happened and few pc's come with a firewire. I have an old pc I drag out when I need the firewire and it's a big pain. What you are trying is experimental and I guess I'd be trying the same thing. Good luck finding simplicity because it's your best bet.

My belief is that it would be inside the scanner itself. In transparency mode the lamp may require more power and shutting off is a safety device if something is failing. Sadly, repairing a scanner costs almost as much as buying a new one.

Did you install the drivers from the disk that came with the scanner? If not, install all the drivers. Was the scanner light moving before, but now it is not? If so, try re-installing the scanner drivers. If that does not work, the registry may have become corrupted, requiring a technician, OR the scanner is broken. You may be able to buy a replacement scanner at a low cost at Walmart, and this option might also cost less than repairing the registry.

Yes, you can detach the lid very easily. Open the lid and when in vertical position, just pull upwards. The lid is held by two metal rods, which will come out when you pull up the lid.

it is supported by only windows XP
so it is advisable to use VMWARE FUSION of BOOTCAMP to install WINDOWS XP
and then connect Scanner to that Virtual Machine.
