[cpia] (no subject)

Hi !
I am trying to use my USB Creative Labs Webcam II with a backport of the 2.3 USB
stack to the 2.2.16 kernel.

The registration of the module using insmod seems to be OK :

Jun 24 15:17:50 linbox kernel: V4L-Driver for Vision CPiA based cameras v1.0.0
Jun 24 15:17:50 linbox kernel: usb.c: registered new driver cpia
Jun 24 15:17:50 linbox kernel: USB CPiA camera found
Jun 24 15:17:50 linbox kernel:   CPiA Version: 1.20 (1.0)
Jun 24 15:17:50 linbox kernel:   CPiA PnP-ID: 0553:0002:0100
Jun 24 15:17:50 linbox kernel:   VP-Version: 1.0 0141

although a "depmod -a" command produces :
/lib/modules/2.2.16/misc/cpia_usb.o: unresolved symbol(s)

Problems are raising when I try to use the cam with xawtv :

[jef@linbox ~]$ xawtv
This is xawtv-3.12, running on Linux/i686 (2.2.16)

and /var/log/messages complains :

and finally, the xawtv window remains black.
I have tried to use other software such as camstream but it also crashes "while
reading image 5".

Any help will be appreciated !
Bye
