[pwc] Logitech quickcam 4000 pro on stargate

["lilianalpr" <>]

Hi!

I'm new to linux and I'm trying to use a Logitech Quickcam 4000 pro on my 
stargate platform (version 7.3, Linux 2.4.19-rmk7-pxa2-star).

I have followed with no success the instructions found at 
http://platformx.sourceforge.net/Documents/Enhancements/Webcam.html

I have also prooved to recompile kernel to produce modules by myself (with 
cross-compiler and by following the stargate manual instructions)

I have searched in internet to find solutions and I have read many answers that 
regards the same issue, but all the proposed solutions don't work for me.

When I start my stargate, dmesg says:

....
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
sa1111_pcibuf: initializing SA-1111 DMA workaround
Pre-allocating 32 buffers for pool 0xc3eea760

usb-ohci.c: USB OHCI at membase 0xf4000400, IRQ 149
usb.c: new USB bus registered, assigned bus number 1

hub.c: 1 port detected
Enabling remote wakeup...
SCSI subsystem driver Revision: 1.00
Initializing USB Mass Storage driver...
usb.c: registered new driver usb-storage
USB Mass Storage support registered.

Then I load the modules by the following:

modprobe videodev 

         (Linux video capture interface: v1.00)

modprobe pwc

         (pwc Philips PCA645/646 + PCVC675/680/690 + PCVC730/740/750 webcam 
module version 8.12 loaded.
          pwc Also supports the Askey VC010, various Logitech Quickcams, 
Samsung MPC-C10 and MPC-C30,
          pwc the Creative WebCam 5, SOTEC Afina Eye and Visionite VCS-UC300 
and VCS-UM100
          usb.c: registered new driver Philips webcam)

insmod -f /lib/modules/linux/kernel/drivers/usb/pwcx-2.4.20.o

        (Warning: kernel-module version mismatch
        /lib/modules/linux/kernel/drivers/usb/pwcx-2.4.20.o was compiled for 
kernel version 2.4.20
        while this kernel is version 2.4.19-rmk7-pxa2-star
        
        pwc Philips webcam decompressor routines version 8.2
        pwc Supports all cameras supported by the main module (pwc). )

Now, when I attach the webcam it displays:

        (USB new device connect on bus1/1, assigned device number 2
         pwc Logitech QuickCam 4000 Pro USB webcam detected.
         pwc Registered as /dev/video0.
         Enabling remote wakeup...)

At this point, a new device is found in /dev/v4l/video0 but it doesn't work!!
Indeed, when I do

vidcat -d /dev/v4l/video0  -o test.ppm

it answers me:

pwc This Logitech QuickCam Pro 4000 camera is equipped with a unknown type of 
sensor (-110).
pwc Failed to set LED on/off time.

And I don't know what I can do to fix the problem!

Please,  any suggestion? Where is the problem?

Tks and sorry for my terrible english
Liliana 

PS
webcam works on my laptop! I use Mandrake and I have installed pwc and v4l2 by 
rpm....
