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

idProduct 0x406c
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.
