Logitech Quickcam Communicate : no /dev/videoX (ArchLinux)

Hi Linux users !

Owning a logitech Quickcam Communicate, I decided to set it up on my ArchLinux box.

I found a PKGBUILD and then compiled the qc-usb26 drivers.

The quickcam module is loaded and seems to work.

[rem@rem ~]$ lsmod | grep quickcam
quickcam               78244  0
videodev                7808  1 quickcam
usbcore               114300  9 ohci_hcd,ehci_hcd,audio,snd_usb_audio,snd_usb_lib,usbhid,uhci_hcd,quickcam
Unfortunately, no /dev/videoX has been created ! (I use UDev)

[rem@rem ~]$ ls /dev
adsp     dsp       hda1       legacy  md0     ram11  random      ttyS0
agpgart  dsp1      hda2       log     mem     ram12  rd          ttyS1
audio    dvd       hda5       loop    misc    ram13  rtc         ttyS2
audio1   dvdrw     hda6       loop0   mixer   ram14  sequencer   ttyS3
cd       fd        hda7       loop1   mixer1  ram15  sequencer2  urandom
cdrom    fd0       hda8       loop2   null    ram2   shm         vc
cdroms   fd0h1200  hdc        loop3   port    ram3   snd         vcc
cdrw     fd0u1440  hw_random  loop4   psaux   ram4   sound       zero
console  fd0u360   ide        loop5   ptmx    ram5   stderr
core     fd0u720   initctl    loop6   pts     ram6   stdin
discs    floppy    input      loop7   ram0    ram7   stdout
disk     full      kmem       mapper  ram1    ram8   tts
dri      hda       kmsg       md      ram10   ram9   tty
Though the cam is recognized since lsusb returns it.
I tried to create a /dev/video0 with that command :

mknod video0 c 81 0
But it didn't work since v4l refuses to use it.

Do you have any clues ?

i had a similar issue with my Logitech Quickcam Express. i downloaded the qc-usb drivers but they just didn't work. However, i downloaded the spca5xx drivers and they worked a charm.

Might be worth checking out.

Thanks for your reply !

I have just installed this spca5xx driver ... unfortunately, I'm still stuck with the same problem ...
Moreover, when I was running a Debian Unstable, the qc-usb driver worked quite well.

Though, something looks strange ; here is what lsusb returns :

[rem@rem dev]$ lsusb
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 003: ID 046d:08f5 Logitech, Inc.
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 003: ID 10d5:0315 Uni Class Technology Co., Ltd
Bus 001 Device 001: ID 0000:0000
Shouldn't I get more informations ?
