    DVB-T USB Tuner

    Hi,

    I've got a USB tuner that I can't seem to get to work.

    lsusb:
    Code:
    Bus 005 Device 003: ID 15a4:9035 Afatech Technologies, Inc.
    dmesg:
    Code:

    [   35.206994] usbcore: registered new interface driver dvb_usb_af9035
    I've opened up the USB stick, the two tuner chips are AF 9033B-N2, it looks exactly the same as this: http://linuxtv.org/wiki/index.php/MS...x_mini_II_V3.0 from the outside. It's branded MobiDTV Dual, serial: MOBIDTVDUAL 150274.

    Is there any chance that I can get this card working? I'm on the latest version of xubuntu (12.10).

    Is your dmesg output with the stick connected from "cold" ? My afatech chipped dvb stick will only properly register from cold. Hot plugging doesn't cut the mustard.....

    For some reason i'm not getting any dvb-usb entries in dmesg now. These are the only entries that refer to the stick:
    Code:
    [ 3117.174623] usb 5-2.2: Product: DVB-T TV Stick
    [ 3117.174628] usb 5-2.2: Manufacturer: ITE Technologies, Inc.
    [ 3117.174633] usb 5-2.2: SerialNumber: AF0102020700001
    lsusb:
    Code:
    Bus 005 Device 005: ID 15a4:1001 Afatech Technologies, Inc. AF9015/AF9035 DVB-T stick
    'dmesg | grep dvb-usb' shows nothing.

    Turn off PC
    Remove stick
    Remove power cable to PC
    Wait a while
    Replace power cable
    Insert stick
    Boot up

    dmesg | grep dvb
    dmesg | grep DVB

    I've tried what you suggested and nothing has changed. I've just noticed that the device id seems to have changed between my first and second post.

    Re: DVB-T USB Tuner

    Um, have you installed the dvb firmware drivers (system > additional drivers)

    Odd about the device id change, that really shouldn't happen. Possible your stick has "two" devices (?) and only one can get picked up by the system?
