--- Canoscan 4400f Driver Download Exclusive Windows 10 64-bit Jun 2026

Canon never released a signed, native Windows 10 64-bit driver for the CanoScan 4400F. When you connect the scanner via USB to a modern 64-bit Windows 10 PC, Windows Update will fail to find a driver, and the device will appear as an "Unknown USB Device" or with a yellow exclamation mark in Device Manager.

Canon officially released a 64-bit driver for the CanoScan 4400F that covers Windows Vista, 7, and 8. While Windows 10 is not always explicitly listed on the older download pages, the Windows 8.1 (64-bit) driver is architecture-compatible with Windows 10.
