Hi Johannes,
Thank you very much for your help. I followed your advice and
mounted the device using fstab. Here is my fstab file:
/dev/sda1 / ext2
defaults 1 1
/dev/cdrom /mnt/cdrom iso9660
noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto
noauto,owner 0 0
none /proc proc
defaults 0 0
none /dev/pts devpts
gid=5,mode=620 0 0
/dev/sda5 swap swap
defaults 0 0
/dev/video /proc/bus/usb usbdevfs
defaults 0 0
However, the gqcam program still cannot recognize the video device:
prompt>gqcam
/dev/video: No such device
Here are my mounted devices:
prompt> mount
/dev/sda1 on / type ext2 (rw)
none on /proc type proc (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/video0 on /proc/bus/usb type usbdevfs (rw)
automount(pid447) on /releases-sgi type autofs
(rw,fd=5,pgrp=447,minproto=2,maxproto=3)
automount(pid463) on /projects type autofs
(rw,fd=5,pgrp=463,minproto=2,maxproto=3)
automount(pid477) on /homes type autofs
(rw,fd=5,pgrp=477,minproto=2,maxproto=3)
automount(pid434) on /distributions type autofs
(rw,fd=5,pgrp=434,minproto=2,maxproto=3)
automount(pid429) on /releases-linux type autofs
(rw,fd=5,pgrp=429,minproto=2,maxproto=3)
hercules:/homes/nikom on /homes/nikom type nfs
(rw,intr,rsize=8192,wsize=8192,addr=137.203.128.5,addr=137.203.128.5)
none on /var/shm type shm (rw)

I thought I need "video0" instead of "video" and recompiled frontend.c
but it did not help.
Do you know what could be wrong?
