Would a wrong power adapter prevent scanning software from seeing the scanner?

From the Umax site, "The power adapter shown here should ONLY be for the Astra 1210P, 3450, 5470, 4400/4450, 6400/6450. The unit shown here is rated for 120 volts AC in, 12 volts DC out at a capacity of 1.7 amps."
Some other Umax scanners use a lower current (0.75A) adapter, so make sure yours supplies enough current (1.7A at 12 volts), otherwise it may actually not work, even if it has enough power for it to appear to power on.
According to http://www.umax.com/support/knowledge/specifications.jsp?model=Astra+6450 , this unit has a Firewire (IEEE1394) connector. Assuming Windows XP, have you verified that you have a IEEE 1394 bus host controller shows up in Device Manager? Have you used the firewire port before, to verify it is functional?

M$You say that the scanning software doesn't see the scanner, does that mean that the operating system (Windows XP, Mac OS X, etc) recognizes the scanner?
If the OS sees it and correctly identifies it, but the scanning software doesn't, it might be time to try some different software.
