[linux-dvb] problem with Hauppauge Dec2000-t under 2.6.0kernel (with CVS updates)

["Michael Jorgenson" <JorgensonMG2@Cardiff.ac.uk>]

Hi All,

I have decided to bite the bullet and start using Fedora on my work laptop
instead of Windows 2000, and after getting most things working, I started trying
to get my DEC2000-T to talk. It worked fine under Win2K on my laptop, and has
pretty good reception here in Cardiff - approx. 40 TV and 30 radio channels
available. However, no luck so far...

I've been reading through the mailing list archive, and believe that the problem
lies with inserting the boot code into the kernel module. I started by upgrading
the kernel to 2.6.0, compiling the source code from www.kernel.org rather than
relying on pre-packaged and patched RPMs. After searching through the mailing
list, I found some messages describing similar problems, and after installing
the ttusb-dec module in debug mode, noticed that the module appeared not to have
the firmware installed. Also, the module caused kernel panic messages when
loaded in debug mode. 

So, I have now tried with the very latest CVS kernel drivers, applied by using
the "make links" script as described in the CVS README file. The single module
version compiles properly. I have installed both the 2000-T and 3000-S firmware
as instructed: ls -l /usr/lib/hotplug/firmware/
total 1368

But, when installing the module dmesg shows:
----

For info, my digibox reports firmware version 0.78, dated 16th October 2002, and
I'm using the UHCI drivers. Laptop is by Samsung, containing mobile P4 chip. 

Please help!

Thanks,
Michael
