The signature, no cap:

void bcm63xx_select_pullup (struct bcm63xx_udc *udc , bool is_on );

• udc — reference to the device controller, the main character here.
• is_on — true to enable the pullup, false to disable it. slay.

🦋 DESCRIPTION 🦋

When the pullup is active, the host will sense a FS/HS device connected to the port — like “hiii bestie, I’m here” 💖. When the pullup is inactive, the host will think the USB device has been disconnected. that’s the whole plot.
