    USB Dual tuner driver issue

    Hi all,

    I have just decided to use the OpenATV image for my VU+ DUO2. I have just installed the Sept 24th build of 4.2. So far all good with one exception. I recently bought a Leadtek USB dual tuner stick. A previous single tuner Leaktek dongle worked fine, however the dual tuner does not. After doing a bit of research we discovered the pci id is "0413:6a05" which is a :-

    Afatech AF9035 demodulator and USB bridge with Dual ITE Tech IT9135 tuners

    Leadtek WinFast DTV Dual Dongle - LinuxTVWiki

    I installed the required drivers, but still no go. The unit is now on load to a friend who has a bit more time up his sleeve than me and he has been looking further into this. This is what he has discovered

    From the dmesg file when the USB tuner is plugged in.

    usb 3-1: new high-speed USB device number 3 using ehci-brcm usb 3-1: dvb_usb_af9035: prechip_version=83 chip_version=02 chip_type=9135 usb 3-1: dvb_usb_v2: found a 'Leadtek WinFast DTV Dongle Dual' in cold state usb 3-1: dvb_usb_v2: downloading firmware from file 'dvb-usb-it9135-02.fw'
    usb 3-1: dvb_usb_af9035: firmware version=3.39.1.0 usb 3-1: dvb_usb_v2: found a 'Leadtek WinFast DTV Dongle Dual' in warm state usb 3-1: dvb_usb_v2: will pass the complete MPEG2 transport stream to the software demuxer
    DVB: registering new adapter (Leadtek WinFast DTV Dongle Dual) i2c i2c-6: af9033: firmware version: LINK=0.0.0.0 OFDM=3.9.1.0 usb 3-1: DVB: registering adapter 2 frontend 0 (Afatech AF9033 (DVB-T))...
    DVB: Unable to find symbol it913x_attach()


    So it's a known device with a valid driver and firmware, but he concludes that the kernel linkage for the DVB registration is broken and thinks the code used is for an earlier kernel revision, so it needs to be corrected for this kernel revision. These are the packages that support the dual tuner

    enigma2-plugin-drivers-dvb-usb-af9035
    kernel-module-dvb-usb-af9035
    firmware-dvb-usb-af9035-02
    firmware-dvb-usb-it913x

    So the question is, who is the best person to forward this information to on this board. Do any of the devs come into this corner of the board? I am aware that this is mainly German board, but unfortunately I do not speak / read or write German.

    Regards,

    Craig

    There are Kernel problems with VU+ Boxes and 4.2 Images. So we offer the 4.2 Images with 2 Kernels. Probably you should try the Image with the old Kernel.

    Try to read this thread with google Translation, if this doesn't work, ask again

    Solved the problem, replaced the Leadtek dual tuner usb dongle with two Haugeppage dual tuner usb sticks. Now have 7 tuners. Current skin doesn't support more then 2 but the lcd display on the duo2 show A-G.

    Hi Thomas4711. Sorry about the username confusion. I am visiting ISOz and used his login by mistake. Bsod is still my normal username.
