It shows driver: bttv,
card:BT878Video (LeadtekWinfast 20),
bus_info: PCI:0000:00:06.0

I queried v4l-info /dev/video*, but the qiockcam is
NOT there.

I browsed /proc/bus/usb and found "Total 0" there.
Further I queried :
" $ cat /var/log/messages |grep video & the result
is:
drivers/usb/core/usb.c: registered new driver usbfs
drivers/usb/core/usb.c: registered new driver hub
drivers/usb/core/usb.c: registered new driver
quickcam
spca50x: no version for "struct_module" found: kernel

spca50x: no version magic, tainting kernel.

I did : $ v4l-conf /dev/video1 & got :
v4l-conf: using X11 display :0.0
dga: version 2.0
mode: 800x600, depth=24, bpp=32, bpl=3200,
base=0xd7000000
/dev/video0 [v4l2]: configuration done .

I tried this and only TV display was there.
Then # lsmod showed these modules :
Module Size Used by
spca50x 140832 0
quickcam 60596 0
usbcore 108468 2 spca50x,quickcam
tuner 17428 0

i2c_core 22020 3
tuner,bttv,i2c_algo_bit
videodev 9728 3 spca50x,quickcam,bttv
I am confused with these messages.Any clues with
these inputs, please.
