The Generic 21BW-2 Scanner appears to refer to a generic or unspecified scanner device, possibly a model that is broadly compatible with Windows systems but not tied to a specific brand. The term "Generic" suggests that the scanner may not have its own proprietary driver and instead uses a standard, broadly compatible driver recognized by Windows. "21BW-2" could be a model number or code for this device.

Typically, such scanners are supported by universal drivers or work with software that can interface with multiple scanner models. For example, many USB scanners are compatible with TWAIN or WIA (Windows Image Acquisition) drivers, both of which are standardized protocols for scanners on Windows.
