My quickcam express is not working in a similar way : ---------------------------------------------------------------------- Having beginners problems with using a webcam - Logitech Quickcam Express. It plugs into a USB port. Kernel version : 2.4.13 with compiled in (modular) support for video4linux and ov511 chipset (not sure if that is the one). Created rpms for xawtv from source (version 3.65) and installed them. Installed qce-ga-0.40b and ran ./quickcam.sh Now I get strange errors when I try to run xawtv : [root@waheguru /dev]# xawtv This is xawtv-3.65, running on Linux/i686 (2.4.13) can't open /dev/video0: No such device v4l-conf had some trouble, trying to continue anyway v4l2: open /dev/video0: No such device v4l: open /dev/video0: No such device no video grabber device available (mind you, I am running the above as root, so there cannot be a permissions problem) The device entries are : crw------- 1 root root 81, 0 Dec 8 03:22 video0 crw------- 1 root root 81, 1 Mar 23 2001 video1 crw------- 1 root root 81, 2 Mar 23 2001 video2 crw------- 1 root root 81, 3 Mar 23 2001 video3 video: total 0 crw------- 1 root root 10, 204 Mar 23 2001 em8300 crw------- 1 root root 10, 206 Mar 23 2001 em8300_ma crw------- 1 root root 10, 205 Mar 23 2001 em8300_mv crw------- 1 root root 10, 207 Mar 23 2001 em8300_sp After loading the modules with quickcam.sh, the list of modules is : [root@waheguru /dev]# lsmod Module Size Used by mod_quickcam 30704 0 (unused) usb-uhci 21264 0 (unused) videodev 4864 0 [mod_quickcam] ipt_MASQUERADE 1776 1 (autoclean) ipt_LOG 3280 1 (autoclean) ipt_state 576 1 (autoclean) iptable_filter 1728 0 (autoclean) (unused) ip_nat_ftp 3632 0 (unused) iptable_nat 19024 1 [ipt_MASQUERADE ip_nat_ftp] ip_conntrack_ftp 3760 0 [ip_nat_ftp] ip_conntrack 20144 3 [ipt_MASQUERADE ipt_state ip_nat_ftp iptable_nat ip_conntrack_ftp] ip_tables 13280 7 [ipt_MASQUERADE ipt_LOG ipt_state iptable_filter iptable_nat] I found an error message in my /var/log/messages : Dec 8 15:16:06 waheguru kernel: hub.c: USB new device connect on bus1/2, assigned device number 3 Dec 8 15:16:06 waheguru kernel: usb.c: USB device 3 (vend/prod 0x46d/0x870) is not claimed by any active driver.

No luck. Could someone figure out what is going on. And suggest a solution. -----------------------------------------------------------------------------------------
