From the project
USB 2.0 timed disconnect adapter with CMOS 555; revision B unbuilt prototype for design review
A USB-A male-to-female adapter intended to simulate unplugging and reconnecting a USB 2.0 peripheral with one button press. A CMOS 555 provides the delay; there is no microcontroller or firmware.
Public design review. Unbuilt prototype; not ready to order. Assembly placement mappings remain unresolved and hardware performance has not been tested. This repository contains only the current revision B source and review material, not previous design iterations or fabrication releases.
