Hi!

I recently purchased a Genius TVGo DVB-T02Q, a usb dvb-t device

 i found in this mail list that this device belongs to the m920x family. The

windows INF file makes reference to the m9207 chip, as frontends, someone
pointed out in this mail list that it has got inside a Zarlink ZL10353 and
MT2060 chipsets, the windows INF file also makes reference to QT1010 and
MT352...

I took a patch i also located in this mail list, but had to modify it a bit
to
make it up-to-date with the current mercury m920x branch of the v4l-dvb
project,... after modification i applied this patch to m920.c file, i send
attached the modified m920.c file.

As a result i found out that the device is recognised by the system, as
stated
in the dmesg output:

[  125.352000] usb 2-3: new high speed USB device using ehci_hcd and address
4
[  125.496000] usb 2-3: configuration #1 chosen from 1 choice
[  125.700000] dvb-usb: found a 'Genius TVGo DVB-T02Q' in cold state, will
try
                                       to load a firmware
[  125.808000] dvb-usb: downloading firmware from file 'dvb-usb-t02q-02.fw'
[  125.812000] usbcore: registered new interface driver dvb_usb_m920x


but the device did not work and the frontends were not loaded, here you are
the related modules automatically loaded when the usb device is connected.


Module                  Size  Used by
dvb_usb_m920x          20484  0
dvb_usb                24972  1 dvb_usb_m920x
dvb_core               80808  1 dvb_usb
dvb_pll                15620  1 dvb_usb

I think the patch only gets the device recognized but is not configured
properly to detect and load the frontends... if I unplug the devive the
modules won't be removed

I'm wokring witha a 2.6.20-15 kernel in a kubuntu system.

I'm willing to make this device work and help in the m920x branch, i'm quite

newbie in programming and then i will need some indications on how to debuge

to get more output from the code or how to try to 'communicate' with the
device (send it stuff and see what comes back).

If anyone else has got some experience with this device, every comment,
suggestion are very wellcome (appart of giving it back and buy a new
one ;)... i'm very stubborn and won't stop trying untill i get this one
working)

cheers,
Pere Blay
