Questions about scanners and Twain

[ThePrIsMcAURA]

Hi,

I just tried to install a PCI-USB card for this guy on his Celeron 400 AT system, i'm pretty sure that it is a socket 7 motherboard. Well anyhow it didn't have USB ports on it so he needed the card. He is running Win98SE for the USB support.
Ok here's the problem. I install the card and win98 detects it and then asks for the win98se disk to install the appropriate drivers. Goes through that no probs and restarts.

I go to install the USB Canon 650U scanner and it doesn't get detected. I try add new hardware search, nothing comes up. I go to install the software for it and then it says TWAIN has not been installed properly.
I took the scanner and installed it on my computer and it went through no probs everything detected. No twain problems
I tried to install a digital video camera but again it wasn't detected.
At this point I have decided that the USB inputs on the card are faulty.

What else I want to clarify is that the TWAIN drivers come with the scanners software or are part of Win98SE.
I understand that TWAIN is a set of command protocols that enable the transfer of data from one device to the computer.
I got that info from www.twain.org and http://www.tafe.sa.edu.au/institutes/torrens-valley/programs/eit/periph/twain.htm
But they didn't state that TWAIN is in the OS or the scanner software.
Or that win98 didn't detect the hardware in the first place the twain protocol was not activated/installed therefor not being able to select any devices in the selection list to install software to.

I don't think it could be his OS's fault because it worked no probs on my system with win98. So its gotta be just the card.

Please clarify what I posted is correct.
THanks in advance.

A Celeron 400 system by definition will not be a Socket 7 system.

Had you have read the manual and the system requirements, you will see that the CanoScan 650U MUST use the motherboard's onboard USB port, and will not work if attached to a USB card. This is supposedly due to the power requirements of the 650U scanner.

The scanner will NOT work with a PCI-USB card.

Complete drivers for the scanner come with the scanner. Just install the CanoScan CS Toolbox.

Thanks for that, didn't see that in the manual actually. I did read through the installation instructions and relative info from it but I didn't see it stated. Oh well that clarifies that.

The computer that is guy got was pretty dodgey, no manuals and software was "backups" so I didn't have any documentation to read about the system.

Thanks for that response
