Making it Work

Firmware

August 21, 2008 - New firmware file fixing the last cause for i2c errors and disconnects and providing a new, more modular i2c request formatting.

You will need the dvb-usb-dib0700-1.20.fw firmware file in /lib/firmware or the relevant place for your distribution.

You may need to change the name of the file to dvb-usb-dib0700-1.10.fw or create a link until the driver code reflects that change.

For archival purposes: dvb-usb-dib0700-1.10.fw firmware file

August 29,2008 - Issues with Firmware 1.20. Some issues have been found with the latest version of the firmware. Users may wish to continue to use 1.10 unless they have patched their v4l-dvb code with dib0700_new_i2c_api.patch.

November 15,2008 - Issues with Firmware 1.20.

• The above mentioned dib0700_new_12c_api.patch is not available discretely but is now rolled into the mercurial drivers
• dvb-usb-dib0700-1.20.fw firmware file is now stable for reception, but remote control functionality is broken; any key press is repeated until the next key is pressed. The only way to get remote control functionality presently is to roll back to 1.10 firmware and suffer the occasional disconnect.
• The mercurial drivers have been changed so they now load 1.20 firmware. To revert to 1.10 firmware you need to rename your firmware file to dvb-usb-dib0700-1.20.fw or provide a link of that name.
• To avoid spurious remote control signals with 1.20 firmware, you need to edit /etc/modprobe.d/options or from Ubuntu onwards /etc/modprobe.d/options.confand add:

options dvb_usb disable-rc-polling=1

November 28,2008 - i2c errors. Changes were made to the remote control drivers on November 16,2008 to correct the repeat key problem. The card is generally stable for dual tuner reception and remote control function with Firmware 1.20.

November 10,2009 - mt2060 I2C write failed. Possible regression of a driver bug raised against Ubuntu running 2.6.27-14 and 2.6.31-2.17 causing mt2060 I2C errors in MythTV useage with firmware 1.20. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/397696 Recommend check the kernel extensions listed here for Low Noise Activation and rc_polling are loaded with correct config file name for your distribution, EIT listings information is turned off until a suitable delay (500ms-1000ms)is added to a single card (not both) and the card has correctly been added to the database as two tuners (no additional NULL entries) in the mythtv recordcard table.

Drivers

It requires the dib0700 driver. Just use Mercurial by following the How to install DVB device drivers instructions.

Forcing the activation of LNAs (Low Noise Amplifier)

You may have to force LNA to get this card working:

In /etc/modprobe.d/options add:

options dvb_usb_dib0700 force_lna_activation=1

Disabling the remote control sensor

You may want to disable the remote control sensor if you are using another one and want to avoid error messages in the logs:

In /etc/modprobe.d/options add:

options dvb_usb disable_rc_polling=1

All relevant kernel modules options

In /etc/modprobe.d/options add:

options [module name] [option name]=[setting]

Get the parameters list using

modinfo [name of kernel module]

Remote Control Support

Genral LIRC settings

Find the IR receiver's device by looking in the dmesg output for a line similar to:

input: IR-receiver inside an USB DVB receiver as /class/input/input4

Additionally, the IR receiver will be listed if you execute the command:

cat /proc/bus/input/devices

For example:

I: Bus=0003 Vendor=2040 Product=9950 Version=0100
N: Name="IR-receiver inside an USB DVB receiver"
P: Phys=usb-0000:07:01.2-1/ir0
S: Sysfs=/class/input/input4
U: Uniq=
H: Handlers=kbd event4 
B: EV=3
B: KEY=14afc336 284284d00000000 0 480058000 219040000801 9e96c000000000 90020000000ffd

In this example, the remote control gives output into /dev/input/event4.

The event number depends on your particular system and can vary.

Eventually this event number can even vary at every reboot.

You could create a new udev rule in /etc/udev/rules.d/65-persistent-hauppauge.rules.

KERNEL=="input*", ATTRS{name}=="IR-receiver inside an USB DVB receiver", SYMLINK+="input/dvb-ir"

It has been mentionned that the following line works, instead of the above line (needs confirmation and deletion of the ugly line):

KERNEL=="event*", ATTRS{name}=="IR-receiver inside an USB DVB receiver", SYMLINK+="input/dvb-ir"

This would make the Hauppauge receiver always always be linked to /dev/input/dvb-ir.

But Linux systems runing recent udev will automatically create non-varying names, a nicer and automatic way of providing a stable input event name:

$ ls -la /dev/input/by-path/
total 0
drwxr-xr-x 2 root root 140 2008-02-07 20:31 .
drwxr-xr-x 4 root root 280 2008-02-07 20:31 ..
lrwxrwxrwx 1 root root   9 2008-02-07 20:31 pci-0000:00:1a.1-usb-0:2:1.0-event-kbd -> ../event1
lrwxrwxrwx 1 root root   9 2008-02-07 20:31 pci-0000:00:1a.1-usb-0:2:1.1-event-mouse -> ../event2

lrwxrwxrwx 1 root root   9 2008-02-07 20:31 platform-pcspkr-event-spkr -> ../event3

LIRC will use it without needing a special kernel module. use the dev/input driver and specify the input event device in /etc/lirc/hardware.conf (the dev/input driver may have been renamed to devinput, you can check this with the command "lircd --device=help"):

# /etc/lirc/hardware.conf
#
# Arguments which will be used when launching lircd
LIRCD_ARGS=""

#Don't start lircmd even if there seems to be a good config file
#START_LIRCMD=false

#Try to load appropriate kernel modules
LOAD_MODULES=true

# Run "lircd --driver=help" for a list of supported drivers.
DRIVER="dev/input"
# If DEVICE is set to /dev/lirc and devfs is in use /dev/lirc/0 will be
# automatically used instead
DEVICE="/dev/input/by-path/pci-4-1--event-ir"
MODULES=""

# Default configuration files for your hardware if any
LIRCD_CONF="/etc/lirc/lircd.conf"

Keys repeated twice

But there is still the problem of the key repeats for it, so that each keypress will be repeated twice. The patches, as mentioned above, may not work, but a workaround is possilbe. It is described in http://ubuntuforums.org/showthread.php?p=4253678

Simply add config = echo " > /dev/null before the main config in .mythtv/lircrc or .lircrc

 begin
  prog = mythtv
  button = Mute
  config = echo " > /dev/null
  config = |
  ...
 end

So each 2nd keypress will be suppressed.

Key Mapping

Heres an example .lircrc file to map button presses to key presses, copy it into your home directory and run irxevent to control any app with the remote (if you have irkick running, quit it before starting irxevent, maybe also su, /etc/init.d/lirc restart).
