Parameters

callback

Callback which is called after scanners are retrieved.

Return Value

The list is broken into two groups, connected devices and undetected devices. The connected devices are detected using the ISIS scanner auto-detection feature. The undetected devices either aren't available or do not support the ISIS scanner auto-detection feature. Many devices cannot be automatically detected, so it is recommended to have a UI element such as a ListBox to show all the devices, not just the connected devices. The two groups will not have overlapping strings.

Although the scanner collection is usually retrieved without user interaction, some scanner drivers might display a message box or other window when they are accessed. For example, an unlicensed driver might display a message about permissions.
