hi,
i'm having difficulty with this tvcard.
i've got linux-2.6.17.1 which supports it.
i'm trying to build a monolithic kernel.
i need to supply tuner=44 to the kernel at boot time.
i think i've configured all the right kernel config
parameters (but i'm not sure) and downloaded the
bluebird usb firmware. but the kernel doesn't find
the firmware and there's no /dev/dvb.
dmesg says:
Linux video capture interface: v1.00

and:
dvb-usb: found a 'DViCO FusionHDTV DVB-T Dual USB' in cold state, will
try to load a firmware
dvb-usb: did not find the firmware file. (dvb-usb-bluebird-01.fw) Please
see linux/Documentation/dvb/ for more details on firmware-problems. (-2)
dvb_usb_cxusb: probe of 1-5:1.0 failed with error -22
i'd put the firmware in both locations that get mentioned:
$ locate dvb-usb-bluebird-01.fw
/lib/firmware/2.6.17.1/dvb-usb-bluebird-01.fw
/lib/hotplug/firmware/dvb-usb-bluebird-01.fw
does anyone know why firmware might not be found?
i also put it in /usr/lib/hotplug/firmware but
it made no difference. i had to create the hotplug
directories. /lib/firmware already existed.
my .config, dmesg, lspci -v and lsusb -v can be seen at:
http://raf.org/dvb/.config
http://raf.org/dvb/dmesg
http://raf.org/dvb/lspci-v
http://raf.org/dvb/lsusb-v
hal-device-manager shows:
CX23880/1/2/3 PCI Video and Audio Decoder [MPEG Port] (driver=cx88-dvb)
CX23880/1/2/3 PCI Video and Audio Decoder (driver=cx8800)
Video Device /dev/vbi0 (subsys=video4linux)
Video Device /dev/video0 (subsys=video4linux)
does this mean the pci tuner and the composite/svideo inputs
are detected? there's no /dev/dvb directory which doesn't
seem good (and mythtv-setup doesn't seem to like things).
can anyone see what i'm doing wrong?
do i need to use the latest mercurial version?
or is the support in 2.6.17.1 adequate for this card?
if i do need the latest version, can it be used in a monolithic kernel?
if so, how? the instructions only seem to refer to building modules.
would overwriting the kernel sources with the latest v4l-dvb work?
if it must be built as modules, do i have do disable dvb/cx88 support
in the kernel source tree before configuring/compiling the latest v4l-dvb?
also, does anyone know exactly what kernel config parameters are needed
to support this card? i don't want to build every module.
the ones i think i need are:
HOTPLUG
I2C_??? (depends on hardware)
VIDEO_DEV
VIDEO_V4L1[_COMPAT]
VIDEO_CX88
VIDEO_CX88_ALSA
VIDEO_CX88_DVB
VIDEO_CX88_DVB_MT352
DVB
DVB_CORE
DVB_USB
DVB_USB_CXUSB
DVB_CX22702
DVB_MT352
many thanks for any help.
cheers,
raf
