hello,
First and foremost, I want to congratulate the Slitaz team for their work. Thanx to Slitaz I was able to resuscitate old PCs which were otherwise gathering dust. And I am amazed how fast these old things can go.
Now for my problem:
I managed to install everything I think was needed to make my usb webcam work with Slitaz. I installed, usbutils, linux-video, libv4l.
$lsusb
$Bus 001 Device 001: ID 046d:08a9 Logitech, Inc. Notebook Deluxe
tazhw detects correctly the right module to install which is gspca-zc3xx
the module gspca-zc3xx loads fine as well as gspca-main. I also add snd-audio-usb so I can use the build in microphone.
but if I plug the webcam here is what I get:
usb 1-1: new full speed USB device using ohci_hcd and address 2
usb 1-1: configuration #1 chosen from 1 choice

and of course the webcam doesn't work, not detected by skype, no video with mplayer etc.
what am I doing wrong?
I can only attach dmesg file since this computer is not mine, it might be difficult to access it. I really don't know what to do since the same webcam was working fine on my Slitaz virtualbox guest at home.
Thanks a lot for any tips you could give me.
