Hi BJ,
currently DirectFB does not support dynamic plugging of USB (or any
other type) devices. This is because the moment that the input libraries
are loaded, a check is done to see which devices are connected; this
check is not performed again at a later date.
If you wish to support this, I suggest to take a look at linux_input.c
and think about how this could be extended; what you want is to add a
new entry to the device_names array, and call driver_open_device with
the new index.
Enabling/Disabling the cursor is done via
IDirectFBDisplayLayer::EnableCursor, I believe.

Hey all, has anybody been able to toggle the cursor on/off at
runtime? For my application their may or may not be a mouse plugged
in at startup so I have to have 'cursor' in my directfbrc file just in
case the user decides to plug one in later. The problem with that is
there is an immovable cursor sitting in the middle of the window now
if there isn't a mouse plugged in. I thought about having a custom
cursor and making it fully transparent when no mouse is connected but
that's a gigantic pain since there is a mouse cursor applied for each
'window' (which my application has lots of due to clickable buttons
and such).
I tried to programmatically move the cursor to an unseen part of the
screen, but the 'eventx' device node isn't available when the mouse is
not connected (obviously), and using /dev/input/mice doesn't seem to
work with the same interface (I can move the cursor programmatically
when it's plugged in).
Any ideas?
BJ
