NAME¶
struct_usb_device_driver - identifies USB device driver to usbcoreSYNOPSIS¶
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¶
nameThe 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.COPYRIGHT¶
