    yes - below is my usbhid.conf file

    Code:
    desktop:~$ nano /etc/modprobe.d/usbhid.conf
      GNU nano 2.0.9        File: /etc/modprobe.d/usbhid.conf
    
    options usbhid quirks=0x15a4:0x1001:0x0004
    I am interested to see the result when I try the USB DVB-T on 32bit plain installs of ubuntu - but I have to wait for a power supply to arrive .

    Re: AF9035 USB DVB-T Karmic 64bit install problem

    For the sake of completeness I also tried to install the stick's driver in my x86_64 Linux installation (2.6.32 kernel) without changing "lib" to "lib64" in the make files v9.08.14.1/installer/AF903x_SRC/Makefile and v9.08.14.1/installer/AF903x_SRC/Makefile.release (see Steps 1 and 3 in my second post) but still making the other changes listed in my second post. It made no discernible difference; the installation script still ran to completion and the console output from the dmesg and lsmod commands were identical to my earlier attempt.

    The "error -12" in the error message "dvb_usb_af903x: probe of 1-1.4:1.0 failed with error -12" displayed by dmesg apparently indicates an ENOMEM error, which means that there was insufficient kernel memory. So it looks like the driver module built under a 64-bit Linux distribution and a 2.6.32 kernel has a memory leak. I don't know whether this is due to building the driver in a 64-bit distribution or whether it is due to building it under a 2.6.32 kernel using the hacks listed in my second post.

    There appears to be a contradiction in the ReadMe.txt file in the v9.08.14.1 directory on the manufacturer's CD: In Section 1 (Release note for this specific version of the manufacturer's software) it states "This release supports x86 32bit and 64bit CPU families in Linux" but in Section 7 (Known problems & limitations) it states "Currently only x86 architecture is supported". Unfortunately I don't have a spare x86_64 PC on which to install a 64-bit distribution with a 2.6.29 or lower kernel in order to see if the driver would install correctly, so I still do not know if my success installing it in a 32-bit Linux installation with a 2.6.28 kernel was down to the 32-bit installation or to the version of the kernel.

    Anyway, I await with interest the outcome of your experiment with a 32-bit edition of Ubuntu and a version of the kernel greater than 2.6.29. You'll almost certainly still have to apply at least my hacks in Steps 2 and 4 of my second post, as the manufacturer's make files and v4l directories only cover up to kernel 2.6.29.

    EDIT (29.12.09 16:06 UTC): Actually, the more I look into it, the more I think it is not a problem of using an x86_64 distribution but rather the version of the kernel. I don't think my hack of using the 2.6.29 kernel af903x driver source code files for the 2.6.30 to 2.6.32 kernel is valid. I don't have a spare PC to install an x86_64 edition of Linux and a 2.6.29 kernel (the stick manufacturer's CD has driver source code for kernels up to 2.6.29), but I would not be surprised if the driver installer worked with that combination.

    just a quick update so you don't think I have given up

    I have just been having no end of problems with my spare P4 unit and it is now sittinng on the table with just psu mobo cpu ram cd and hd running seatools from ubcd4.1.1.

    hopefully I can find the problem I am having with it soon and get a 32bit 8.04.2 installed on it to continue looking for the USB DVB-T solution

    Re: AF9035 USB DVB-T Karmic 64bit install problem

    p4 problem seemed to be the speed the default bios settings were setting for the RAM on Auto. system running 32bit 8.04.02 , hair on my head less

    unrared the files and in a terminal
    Code:
    sh ITE-Linux-AF903x-v9.08.14.1.sh
    it ran to the end , but spat out a lot of errors - but lsmod | more showed the AF903x DVB-T modules.

    I then installed Kaffeine , when told me it could not detect a DVB-T device.

    I restarted the machine , and then Kaffiene detected the DVB-T device and I have been able to scan channels.

    dmesg output is

    Code:
    [   47.585771] dvb-usb: found a 'ITEtech USB2.0 DVB-T Recevier' in warm state.
    [   47.681588] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.

    usbcore               146412  6 dvb_usb_af903x,dvb_usb,usbhid,ehci_hcd,ohci_hcd

    I am just scanning channels at the moment and thinking about trying a 9.10 32 bit installation.

    Re: AF9035 USB DVB-T Karmic 64bit install problem

    I installed 9.10 32bit with the same results as 64bit

    it does seem to be the kernal version that causes the problem

    in the readme for the 9035.linux.PC.dvb-tV9.07.10.1 , the revision history says

    (3) Support kernel 2.6.29.

    it is a bit of a paiin that upgrading the kernal causes there issues


    any suggestions , I am willing to try as I have the P4 I can load with anything.

    I had thought to tru mythbuntu 9.10 , but I assume it will have the same issues because of its kernal version

    Re: AF9035 USB DVB-T Karmic 64bit install problem

    The driver's lack of support for the 2.6.30 and upwards kernels is definitely the problem. I gave up waiting for a reply from the manufacturer's support team to my e-mail. I called it a day for that model and bought an AVerTV Volar Black HD A850, which works with Linux kernel 2.6.30 and upwards. There is no mention of Linux in either the installation guide or the CD that came with the HD A850 stick. However, I googled the missing firmware file name "dvb-usb-af9015.fw" and found a link to the firmware file on the linuxtv.org Wiki site. I dowloaded dvb-usb-af9015.fw from the link given on the page http://linuxtv.org/wiki/index.php/DVB-T_USB_Devices and copied it to /lib64/firmware/ and everything works the way it should. I'll find a good home for the EZTV860 with a Windows user.

    I have ordered this device from DealExtreme and was hoping it would work with my Ubuntu HTPC. Thanks for this thread...

    I also need the file
    Code:
    9035.linux.PC.dvb-tV9.07.10.1.zip
    . If anyone has this can they please put a link up and post it online. I think this file is in danger of extinction!

    I am attaching driver v9.08.14.1 for anyone interested. I got the driver after sending email to ITE support department. It is the latest available driver.
