[cpia] problems with intel playcam

[Robert Ladstaetter]

hi,

i've successfully installed the terracam usb webcam, and after that I wanted
to do the same with the intel playcam (me2cam, which is said to be supported
too by the cpia driver); 

kernel: 2.3.99pre9

everything loads ok, but in

/var/log/messages i get:

Aug 31 11:49:16 dmt kernel: usb.c: USB new device connect, assigned device
number 2
Aug 31 11:49:16 dmt kernel: usb.c: kmalloc IF c5b78ec0, numif 1  
Aug 31 11:49:16 dmt kernel: usb.c: new device strings: Mfr=0, Product=0,
SerialNumber=0
Aug 31 11:49:16 dmt kernel: usb.c: unhandled interfaces on device
Aug 31 11:49:16 dmt kernel: usb.c: This device is not recognized by any
installed USB driver.

<this line doesn't sound all too good, then I get more stuff like:>

Aug 31 11:49:16 dmt kernel:   DescriptorType      = 01

[....] (about 100 lines)

if I load usbcore, videodev, cpia and cpia_usb the directory /proc/cpia 
exists, but is empty (?). if I make a 'cat /dev/video' everything I get is an
'Unknown Device/Device doesn't exist'. Unfortunately in the docs the only
thing which relates to this problem is the line: 'everything should be detected
automatically'. Well, that obviously isn't the case. ;-). 

I suspekt that the camera doesn't function, but maybe this is a common problem
with an easy solution. *crosses his fingers*

the terracam worked right out of the box, but on another machine I right now
don't have access to. (very unfortunate ;-)

greetings from austria,

robert
