hey worms- I had trouble installing the driver in W2k for the firewire card. I got "data is invalid" error. I finally found this info ~
fix: This error appears to be due to a protection problem in the Windows registry and can occur with a variety of drivers (sound cards and SCSI drivers have been reported).
To fix this problem,
go to Start, Run... and type "regedt32" without the quotes to run the Registry Editor. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ENUM\PCI and you will see a number of keys of the form "VEN_xxxx", where xxxx are strings like "1102&DEV_0004&SUBSYS_00011103&REV_04".
Under each of these folders will be another folder with a long numerical name. Open each folder and look for the "DeviceDesc" which matches the hardware you are trying to install. Right Click on the "VEN_xxxx" for that device and select 'Permissions' and then tick "Allow" for "Full Control". Close Regedit and then continue with the installation of your device.
Now I am no registery hacker pro but this is simple and it worked perfectly, and this scanner kicks butt. I just bought a second one for home. btw the deal is still valid
