13 the peripheral being disconnected

16 Disables the D+ (or potentially D-) pullup, which the host may see as a
17 disconnect (when a VBUS session is active). Not all systems support
18 software pullup controls.

20 This routine may be used during the gadget driver bind call to prevent
21 the peripheral from ever being visible to the USB host, unless later
22 usb_gadget_connect is called. For example, user mode components may
23 need to be activated before the system can talk to hosts.
