I do remember this error message (timeout on ep4in).
I got it when I unloaded
then reloaded the module after a failed loading attempt
(hotplug scripts not installed). Power cycling the device
before unloading the driver solved the problem,
but I assume it doesn't here.

Certainly, son. Windows knows much better what time
it is than you do. And you better believe it, because
no more OfficeXP for you if you don't.

AFAIK it will still need the hotplug scripts even when
compiled into the kernel. I use the hotplug-scripts
distribution of January 5 2004; you can try them out
using

wget http://switch.dl.sourceforge.net/sourceforge/linux-hotplug/hotplug-2004_01_05.tar.gz
tar -xzf hotplug-2004_01_05.tar.gz
cd hotplug-2004_01_05
make install

last line as root. Better deinstall the gentoo'ized package
first, too.

Behaviour under linux (at least for me) is different: Audio
and Video on the TV, remote does nothing.

I will go check the filesize on my firmware when I get
home, just to make sure there aren't multiple
different 2.15a's floating around.

Sincerely,
Roland
