3) Program starts and then just does nothing
--------------------------------------------
This is what the program is supposed to do. After you started it will
give you basically two devices, a new /dev/input/eventX and a
/dev/input/jsX. You can access and test your controller with jstest
and evtest applications. Or in case you want just see if your driver
is working correctly you can pass the -v option:
and evtest applications (available from your distribution or in the
tools/ subdirectory). Or in case you want just see if your driver is
working correctly you can pass the -v option:
% ./xboxdrv -v
% ./xboxdrv -v
This will cause the driver to output all the events that it received
from the controller.

* document /dev/input/eventX device

* add jstest, evtest into the source
* disconnecting the pad in use will just let the driver wait forever

.SH NAME
jstest \- joystick test program
.SH SYNOPSIS
.B jstest
[--normal] [--old] [--event] [--nonblock] [--select] <device-name>
.SH DESCRIPTION
.B jstest
can be used to test all the features of the Linux
joystick API, including non-blocking and \fBselect\fP(2) access, as
well as version 0.x compatibility mode.
.PP
It is also intended to
serve as an example implementation for those who wish to learn
how to write their own joystick using applications.
.SH OPTIONS
.TP
.I \--normal
One-line mode showing immediate status.
.TP
.I \--old
Same as --normal, using 0.x interface.
.TP
.I \--event
Prints events as they come in.
.TP
.I \--nonblock
Same as --event, in nonblocking mode.
.TP
.I \--select
Same as --event, using \fBselect\fP(2) call.
.SH SEE ALSO
\fBjscal\fP(1), \fBinputattach\fP(1), \fBselect\fP(2).
