Same thing on last fedora, with ekiga3, vlc or cheese.
And always the strange behaviour (register value aren't the defaults
value) when the module is automatically load.
With a manual load or a reload (modprobe), it works fine.
The difference between a automatically reload (Fn Keys) and manual
reload (modprobe) is the disconnect sequence.
If i skip this sequence in m5602_po1030.c, my problem disappear
void po1030_disconnect(struct sd *sd)
{
// sd->sensor = NULL;
// kfree(sd->sensor_priv);
}

Laurent
