Pues nada ninguno de esos componentes te dara 5 voltios.
En mi opinion prueba con 5 voltios externos, si va bien entonces ya te preocupas o de buscarlos internos o bien de añadir un regulador de tension, el LM7805 seria perfecto:

Supongo tu alimentador es como el del ct5365 y da 18 voltios continua en el secundario.
Saludos.
Lo he intentado haciéndolo como me has comentado y nada. No me detecta ningún dispositivo en el dmesg.
Quizás lo esté haciendo mal: He intentando coger sólo de la placa del D+ y el D- y de un cargador usb (comprobados los 5V) he cogido VCC y GND.
