.SH "MEMBERS"
.PP
name
.RS 4
The driver name should be unique among USB drivers, and should normally be the same as the module name\&.
.RE
.PP
probe
.RS 4
Called to see if the driver is willing to manage a particular device\&. If it is, probe returns zero and uses
\fBdev_set_drvdata\fR
to associate driver\-specific data with the device\&. If unwilling to manage the device, return a negative errno value\&.
.RE
.PP
disconnect
.RS 4
Called when the device is no longer accessible, usually because it has been (or is being) disconnected or the driver\*(Aqs module is being unloaded\&.
.RE
.PP
suspend
.RS 4
Called when the device is going to be suspended by the system\&.
.RE
.PP
resume
.RS 4
Called when the device is being resumed by the system\&.
.RE
.PP
drvwrap
.RS 4
Driver\-model core structure wrapper\&.
.RE
.PP
supports_autosuspend
.RS 4
if set to 0, the USB core will not allow autosuspend for devices bound to this driver\&.
.RE
.SH "DESCRIPTION"
.PP
USB drivers must provide all the fields listed above except drvwrap\&.
