Hi crew!

I've always used my logitech camera with uvc driver and everything was 
really perfect (thanks!).

Last week I received a  "Terratec Cinergy T USB XS" usb key and of 
course I've tryed to make it work. :D

This dvb hardware works with em28xx module, so I had to compile it and 
install.

The problem is that after such installation, I can not longer use my 
camera, because I receive the following error (if I try to reload uvc 
module):

> # modprobe uvcvideo
> FATAL: Error inserting uvcvideo 
> (/lib/modules/2.6.22-rc3-k7/usb/media/uvcvideo.ko): Unknown symbol in 
> module, or unknown parameter (see dmesg)
Infact, if I run dmesg, I can see:

> em28xx v4l2 driver version 0.0.1 loaded
> usbcore: registered new interface driver em28xx
> uvcvideo: disagrees about version of symbol video_devdata
> uvcvideo: Unknown symbol video_devdata
> uvcvideo: disagrees about version of symbol video_unregister_device
> uvcvideo: Unknown symbol video_unregister_device
> uvcvideo: disagrees about version of symbol video_device_alloc
> uvcvideo: Unknown symbol video_device_alloc
> uvcvideo: disagrees about version of symbol video_register_device
> uvcvideo: Unknown symbol video_register_device
> uvcvideo: disagrees about version of symbol video_device_release
> uvcvideo: Unknown symbol video_device_release

I suspect that both video devices want to use the same /dev/video 
address, but I'm not sure at all.

What do you suggest to do?

Thank you,

giopas

ps: I run Debian SID/Experimental, both drivers are compiled from last 
avaible svn/hg revisions, I found such errors both with 2.6.22 and 
2.6.21 kernels.
