Hi, dvb professionals,

I followed the advices on
http://www.linuxtv.org/wiki/index.php/How_to_Obtain%2C_Build_and_Install_V4L-DVB_Device_Drivers#Optional_Pre-Compilation_Steps

Build and Installation Instructions

downloaded the v4l sources via mercurial,
"make" and "sudo make install" finished without error messages.

rebooted the computer

dmesg shows the device:

---
usb 2-1: new high speed USB device using ehci_hcd and address 6
usb 2-1: configuration #1 chosen from 1 choice
usb 2-1: New USB device found, idVendor=0b48, idProduct=300d
usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 2-1: Product: TT-USB2.0
usb 2-1: Manufacturer: TechnoTrend
usb 2-1: SerialNumber: LHKAMG
---

no error if I unplug and plug it on USB again

the connected box is a TechnoTrend CT 3560 CI
I googled and found chipset names like TDA8274 + TDA10023
did not find anything in wiki, so I could not determine module or driver
names to be identified with lsmod.

there is no created /dev/dvb or /dev/video device

google did not help me answering the question "do I need firmware, and
if so where to get it"

uname -a shows
Linux rolf9 2.6.28-7.slh.6-sidux-686 #1 SMP PREEMPT Sat Mar 14 02:30:40
UTC 2009 i686 GNU/Linux

for now I got stuck.

Do you know of a next step towards having tv on my laptop?

I don't think the product is supported.  Just to be clear, you can't
just modprobe the chip driver for whatever components happen to be in
your device and expect it to work.

If you are lucky enough to have a product where all the chipset
drivers are already written, then a developer needs to write a device
profile in the bridge driver.  However, if it uses some components
that are not supported, then it's a lot more work since an entire new
driver needs to be written.

If you want to help make it work, you should start by creating a page
in the linuxtv.org wiki, and include high resolution digital photos of
the circuit board, so people can get an accurate inventory of what
chips are in the device in question.  From there, perhaps a developer
interested in adding the support can do the driver work.

Cheers,

Devin
