USB scanning requires scan drivers. The only way to get scan drivers is to check HPs downloads and drivers area for your OS. If scan drivers are not available in that area then you will need to perform MS updates and pull compatbile drivers from MS. Once you have drivers installed then you can use either HP scanning applications (full software solution) or 3rd party scan applications to complete your scan jobs.
