STRUCT USB_DEVICE_DR(9) Host-Side Data Types and Macro STRUCT USB_DEVICE_DR(9)NAMEstruct_usb_device_driver - identifies USB device driver to usbcore
SYNOPSIS
struct usb_device_driver {
const char * name;
int (* probe) (struct usb_device *udev);
void (* disconnect) (struct usb_device *udev);
int (* suspend) (struct usb_device *udev, pm_message_t message);
int (* resume) (struct usb_device *udev, pm_message_t message);
struct usbdrv_wrap drvwrap;
unsigned int supports_autosuspend:1;
};
MEMBERS
name
The driver name should be unique among USB drivers, and should
normally be the same as the module name.
probe
Called to see if the driver is willing to manage a particular
device. If it is, probe returns zero and uses dev_set_drvdata to
associate driver-specific data with the device. If unwilling to
manage the device, return a negative errno value.
disconnect
Called when the device is no longer accessible, usually because it
has been (or is being) disconnected or the driver´s module is being
unloaded.
suspend
Called when the device is going to be suspended by the system.
resume
Called when the device is being resumed by the system.
drvwrap
Driver-model core structure wrapper.
supports_autosuspend
if set to 0, the USB core will not allow autosuspend for devices
bound to this driver.
DESCRIPTION
USB drivers must provide all the fields listed above except drvwrap.
