Hauppauge WinTV-NOVA-T-500

This is a Hauppauge Dual-tuner PCI card. It's actually a USB device, with the host USB controller and USB dual-tuner on a single PCI card. There aren't any real USB plugs or sockets involved. See DVB_USB for further details

Some cards suffer from a serious problem. The USB DVB-T tuners seem to occasionally "disconnect" and reconnect during a tuning operation. In Linux 2.6.21 and earlier, this causes the kernel to oops requiring a reboot. If you apply all these patches 1 2 3 then you won't get a kernel oops - instead, your LinuxDVB application will just stop working. Exiting and restarting your application (more accurately, closing all the LinuxDVB devices and then waiting a second) should make everything work again.

Scanning (or tuning with any AUTO parameters) is known to be broken in kernel 2.6.20, and probably earlier kernels too. Fixed in kernel 2.6.21; try [this patch] for older kernels.

I've got 2 of these, which are different revisions of the board. This one is rock solid:

$ lspci
00:13.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 61)
00:13.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 61)
00:13.2 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 63)

This one has the random USB disconnects problem:

$ lspci
00:13.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 62)
00:13.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 62)
00:13.2 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 65)

Note that USB controller chip is a different revision number.

July 30, 2007 - In order to fix the disconnects and get proper remote control support, you should apply the following patches in that order to the v4l-dvb tree:

     * MT1060_IF1_freq_set.diff - 2.3K
             * Sets the MT2060 IF1 frequency according to the calibration values stored in the EEPROM. It is supposed to enhance the signal quality

     * dibcom2.diff - 1.2K
             * fix disconnects for NOVA-T-500 and NOVA-TD

             * Post: http://linuxtv.org/pipermail/linux-dvb/2007-July/019284.html
     * nova-td_remote.diff - 2.6K
             * Add remote keymap for the Hauppauge Nova-TD Stick
             * Janne Grunau
             * Post: http://linuxtv.org/pipermail/linux-dvb/2007-July/019349.html
     * nova-t500_remote.diff  - 760B
             * Add remote control support for the Hauppauge Nova-T 500
             * Janne Grunau
             * Post: http://linuxtv.org/pipermail/linux-dvb/2007-July/019349.html

YMMV,,,

thanks for work by Olivier Danet, Janne Grunau and Jose Alberto Reguero.

you may want/need to turn on the on-board amplifier:

sudo gedit /etc/modprobe.d/options
Add: options dvb-usb-dib0700 force_lna_activation=1
