What is a Bulk USB Device Windows Driver?

A Bulk USB Device Windows Driver is a type of driver that facilitates communication between a computer running Windows and a USB device that uses the Bulk transfer mode. This mode is used for large, non-time-sensitive data transfers, such as between a computer and a storage device, printer, scanner, or other USB peripherals. Devices that use Bulk transfers typically require drivers that allow the operating system to manage data flow efficiently.

When Windows detects a new USB device, it tries to automatically install the appropriate driver. However, in some cases, especially with non-standard or less commonly used devices, you may need to manually install or update the Bulk USB Device driver.
