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¶
