Question about HP External USB DVD-RW drive

Hello, the USB external DVD-RW drive requires a connection to a computer via USB 2.0 to work. Video projectors generally don't have USB ports compatible with external optical drives, so you have to use a computer to play back films [^1^].

[^1^]: The information available indicates that these external drives connect exclusively to computers via USB (HP F2B56AA and similar models in the results). No mention of direct compatibility with projectors.
