g_usb_context_enumerate ()

void
g_usb_context_enumerate (GUsbContext *context);

Enumerates all the USB devices and adds them to the context.

You only need to call this function once, and any subsequent calls are silently ignored.

Since: 0.2.2

g_usb_context_set_debug ()

void
g_usb_context_set_debug (GUsbContext *context,
                         GLogLevelFlags flags);

Sets the debug flags which control what is logged to the console.

Using G_LOG_LEVEL_INFO will output to standard out, and everything else logs to standard error.

Since: 0.1.0

g_usb_context_find_by_bus_address (GUsbContext *context,
                                   guint8 bus,
                                   guint8 address,
                                   GError **error);

Finds a device based on its bus and address values.

Since: 0.2.2

g_usb_context_find_by_vid_pid ()

GUsbDevice *
g_usb_context_find_by_vid_pid (GUsbContext *context,
                               guint16 vid,
                               guint16 pid,
                               GError **error);

Finds a device based on its bus and address values.

Since: 0.2.2

g_usb_context_find_by_platform_id ()

GUsbDevice *
g_usb_context_find_by_platform_id (GUsbContext *context,
                                   const gchar *platform_id,
                                   GError **error);

Finds a device based on its platform id value.

Since: 0.2.4

g_usb_context_wait_for_replug ()

GUsbDevice *
g_usb_context_wait_for_replug (GUsbContext *context,
                               GUsbDevice *device,
