Driver adventures for a 1999 webcam (blog.benjojo.co.uk)

Article summary

The author attempted to revive a 1999 Logitech QuickCam Express webcam by writing a user space driver, as the official drivers only supported up to Windows XP. The process involved reverse engineering the USB protocol and decoding the image data. The author successfully streamed images from the webcam, but the quality was not optimal due to the camera's outdated sensor and lack of proper debayering. The project demonstrates the possibility of breathing new life into old hardware with custom drivers.
