I downloaded version from tevii.com and it worked for me on laptop
running win 7.  Had problems with HD on an XP machine but I assumed it
was because the video card was old/slow.

I tried on Ubuntu 9.10 but had problems which I documented here on 16
april. Loading the firmware worked fine but there were problems with
remote control messages being logged continually as well as stability
problems. The card would tune (with scan) and worked with mythtv (for a
day or so)

I didn't touch rules.d

Had no problem with Ubuntu recognising the device and the correct .fw
file being downloaded.

There are various versions of dw2102.c from tevii, etc.  I think I tried
all of them. I did change the timeout on RC messages (dw2102.c?) which
helped but did not cure the problem.

Also tried the s2-liplianin library as well which seemed promising but
also did not cure the problem.

I didn't have the knowledge (or time) to decide if the problem was in
the firmware or the v4l drivers or perhaps some strange interaction with
my dvb-t usb box.

Exchanged some emails with tevii guys who had posted here however they
appear to take the view that if it works under windows then the device
is fine and offer no other solution.

In the end I bought a Nova S2 PCI card which works fine but would be
interested in trying to get the S660 working.
