Message-ID: <4D6E68D1.6050209@wp.pl> (raw)

Hi there,
I just got an Creative VGA (640x480) USB Live Webcam, VF0520.

lsusb (partial):

Bus 003 Device 007: ID 041e:406c Creative Technology, Ltd
Device Descriptor:
  bLength                18

  bDeviceClass          239 Miscellaneous Device
  bDeviceSubClass         2 ?

  idVendor           0x041e Creative Technology, Ltd

  bcdDevice           10.19
  iManufacturer           1 Creative Labs
  iProduct                3 VF0520 Live! Cam Sync
  iSerial                 0
  bNumConfigurations      1

lsmod | grep vid:
uvcvideo               50184  0
compat_ioctl32          5120  1 uvcvideo
videodev               32000  1 uvcvideo
v4l1_compat            15876  2 uvcvideo,videodev

uname -a (kernel from Fedora 10):
[root@laurent-home ~]# uname -a
Linux laurent-home 2.6.27.5-117.fc10.i686 #1 SMP Tue Nov 18 12:19:59 EST
2008 i686 athlon i386 GNU/Linux

Problem: device nodes are created, but NO video in gmplayer, tvtime
complains: can't open /dev/video0.

Only trace in syslog is:

Mar  2 16:26:56 laurent-home kernel: uvcvideo: Failed to submit URB 0 (-28).

Webcam is connected to VIA USB 2.0 controller through a USB 2.0 hub.

What is strange, two days ago I tried apparently the same (model VFxxxx)
with SUCCESS.
Device seems working in Windoze (Ekiga).

What should I check/ do?

W.P.
