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 fileis 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.
- Silence unknown keycodes
- When an unknown key code is received (from another remote, like the receiver's or the TV's), it is not eaten and the module keeps yelling about it. This patch stops the yelling.
- Jonas Anden, Thu Aug 2 00:28:17 CEST 2007
- This patch is not cleanly applicable, but it is an easy one-liner to do by hand.
- This patch is regarded as not really being the proper fix; it just limits the effect of bad behaviour.
- This patch is not to be used with the following patch.
- This patch should be deprecated once the following patch has seen more testing.
- Key repeat for dib0700 IR receiver
- Solves remote toggle bit stuff and implements repeated key feature (with repeat delay to avoid unwanted double hits) for rc-5 and nec protocols. It also contains some keymap for the remotes used for testing (a philipps compatible rc5 remote and a teac nec remote). They are far from being complete since I've used them just for testing.
- Filippo Argiolas, Tue Feb 19 16:17:55 CET 2008
- This patch is not to be used with the previous patch.
- This patch is prefered over the previous patch.
Note for WinTV Nova-T-500 users: the current drivers are close to stable at the moment (2008-01-25). Occasional USB disconnects may still be experienced. The disconnects were caused by disabling the pull-down resistors or unintentional writes from the dib0700 bridge to the usb bus when accidentally hitting the end of a SOF packet. Why and when this happens can only be debugged by the dibcom firmware guys [1] . Other possible reasons for bad behavior could be bad reception (check your aerial, cabling, splitters and low-cost amplifiers) and EIT scanning. Search the linux-dvb mailing list for more information and current problems being experienced.
On-board amplifier for Nova-T-500
You may want/need to turn on the on-board amplifier:
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]
The debug values are bit fields, with each bit representing a different category. Add values to turn on multiple debugging categories. 15.

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"
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 pci-0000:00:1a.1-usb-0:2:1.1-mouse -> ../mouse1 lrwxrwxrwx 1 root root 9 2008-02-07 20:31 pci-4-1--event-ir -> ../event4 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:
# /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" LIRCMD_CONF=""
Here is a proper lircd.conf:
#
# brand: Hauppauge
# model no. of remote control: 45 buttons Snowboard Shape Silver over Black
