I have a fileserver appliance with HTS TVHeadend built into it as a streaming tv server. XBMC clients are the frontends.
I got a new dual tuner card the other day. It is a PCI card, but the trouble is that it is 2 USB tuners connected via the PCI bus. The autosuspend USB feature causes problems with one or both tuners dropping out.
I've tried this:
echo -n -1 > /sys/module/usbcore/parameters/autosuspend
to disable the autosuspsend, but I still had problems with the tuner card flaking out.
I have read that appending options usbcore autosuspend=0 to /etc/modprobe.d/options
will work, but I don't have /etc/modprobe.d/options
