usb_client_attach(9F) Kernel Functions usb_client_attach(9F)
NAME
usb_client_attach, usb_client_detach - USBA framework registration of
client USB drivers
SYNOPSIS
#define USBDRV_MAJOR_VER <major>
#define USBDRV_MINOR_VER <minor>
#include <sys/usb/usba.h>
int usb_client_attach(dev_info_t *dip,
uint_t version, usb_flags_t flags);
void usb_client_detach(dev_info_t *dip,
usb_client_dev_data_t *dev_data);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
PARAMETERS
For usb_client_attach():
dip Pointer to the device's dev_info structure.
version Must be set to USBDRV_VERSION. (See below.)
flags Not used.
For usb_client_detach():
dip Pointer to the device's dev_info structure.
dev_data Pointer to a usb_client_dev_data_t to free. Can be NULL.
DESCRIPTION
The usb_client_attach() function registers a driver with the USBA
framework and must be called before any other USBA function. Usually,
usb_client_attach() is followed by a call to usb_get_dev_data(9F).
The usb_client_detach() function unregisters a driver with the USBA
framework. The usb_client_detach() function releases memory for all
strings, descriptors and trees set up by usb_get_dev_data(9F) when its
dev_data argument is non-NULL. The usb_client_detach() function is the
last USBA function a client calls before completing detach(9E). It is
not necessary to call usb_client_detach() during a suspend operation.
VERSIONING
USBDRV_VERSION is a macro which creates a version number based on the
USBDRV_MAJOR_VER and USBDRV_MINOR_VER definitions. It must be passed as
the version argument.
For drivers version 2.0 or greater, the value of USBDRV_MAJOR_VERSION
must match its corresponding USBA_MAJOR_VER value in <sys/usb/usbai.h>,
and the value of USBDRV_MINOR_VERSION must not be greater than its cor‐
responding USBA_MINOR_VER value also in <sys/usb/usbai.h>.
Version 0.8 drivers from previous releases are binary compatible and
run on Solaris 10, but are not compilable. Version 0.8 binary compati‐
bility will not be supported in subsequent Solaris OS releases.
Definitions of USBDRV_MAJOR_VERSION and USBDRV_MINOR_VERSION must
appear in the client driver above the reference to <sys/usb/usba.h>.
Note that different releases have different USBA_[MAJOR|MINOR]_VER num‐
bers.
RETURN VALUES
For usb_client_attach():
USB_SUCCESS Registration is successful.
USB_INVALID_ARGS dip is NULL.
USB_INVALID_CONTEXT Called from interrupt context. Not called from
an attach routine context.
USB_INVALID_VERSION Version passed in version is invalid.
USB_FAILURE Other internal error.
For usb_client_detach():
USB_INVALID_ARGS dip is NULL.
USB_INVALID_CONTEXT Not called from an attach routine context.
CONTEXT
The usb_client_attach() function may only be called from attach(9E).
The usb_client_detach() function may be called only from attach(9E) or
detach(9E).
EXAMPLES
if (usb_client_attach(dip, USBDRV_VERSION, 0) != USB_SUCCESS) {
cmn_err (CE_WARN, "%s%d: Couldn't register USB device",
ddi_driver_name(dip), ddi_get_instance(dip));
return (USB_FAILURE);
}
if (usb_get_dev_data(dip, &dev_data, USB_PARSE_LVL_IF, 0) !=
USB_SUCCESS) {
cmn_err (CE_WARN, "%s%d: Couldn't get device descriptor data.",
ddi_driver_name(dip), ddi_get_instance(dip));
return (USB_FAILURE);
}
