[linux-dvb] Driver for dvb-T via usb : 1164:2efc

Hi,

I've recently buyed a Emtec 810S DVB-T usb dongle and tried to make it work,
operation which ended quite satisfactory.

So i would like to share my knowledge with your team as your drivers development effort also helped
me to render my Usb Stick usable.

I've downloaded the actual status of the mercurial at : http://linuxtv.org/hg/v4l-dvb
and modified the source to add the usb ids to the driver :

- At the time of doing "hg clone", the head was :
changeset:   7115:3f704aa9d92e
tag:         tip
date:        Tue Jan 29 16:32:35 2008 -0200

- The patch is attached (if you don't like attachments in this mailing list, all my apologies)

I'm running linux kernel 2.6.23.14, using distro Debian Etch, kaffeine as a TV viewer.

So I compiled the drivers and did overwrite (make install) the current kernel modules.
I placed the firmware file dvb-usb-dib0700-03-pre1.fw from Patrick Boettcher in /lib/firmware,
following the renaming recommendation (dvb-usb-dib0700-1.10.fw).

So now everything is working quite fine.

The only issue is that after some channel zapping or even immediately, the tuner does no longer respond, 
kaffeine hangs, modules cannot be unloaded even with rmmod -f (the dongle being disconnected). 
The lsusb command hangs also.

Only rebooting helps (and sucks).

kernel messages at startup are :
Feb  1 17:34:47 aroos kernel: usb 1-5: new high speed USB device using ehci_hcd
and address 5
Feb  1 17:34:47 aroos kernel: usb 1-5: configuration #1 chosen from 1 choice
Feb  1 17:34:48 aroos kernel: dib0700: loaded with support for 7 different device-types

Feb  1 17:34:49 aroos kernel: dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
Feb  1 17:34:49 aroos kernel: DVB: registering new adapter (Emtec S810)
Feb  1 17:34:49 aroos kernel: DVB: registering frontend 0 (DiBcom 7000PC)...
Feb  1 17:34:49 aroos kernel: DiB0070: successfully identified
Feb  1 17:34:49 aroos kernel: dvb-usb: Emtec S810 successfully initialized and connected.
Feb  1 17:34:49 aroos kernel: usbcore: registered new interface driver dvb_usb_dib0700p

The lsusb output is attached.

The chips on the board are :
DIBcom 7070PB1-AXGXba-G-a
and
DIBcom 0700C-XCXXa-G

I would be most grateful if someone has an idea about improving the stability of the driver.

Also I've found in the archives a thread : http://www.linuxtv.org/pipermail/linux-dvb/2007-January/015525.html
involving Patrick Boettcher and Michael Wünscher about a similar device (I had the same driver information
under Windows).

Maybe the conclusions here would also help that other topic, however I did not see the USB Ids from these messages
in dvb-usb-ids.h 

Thank in advance for your help and time !

Best regards,
