Probe error on 0c45:628f

[lennart...@googlemail.com]

Operating System: ubuntu 8.10
Kernel: 2.6.27
Model: 0c45:628f

Everything regarding compilation and installing the module worked out
fine. Though the /dev/video0 device is not created nor does it work
when i create it myself. The dmesg puts up the following log when
loading the module:

[ 3518.178805] microdia: Microdia USB 2.0 webcam driver loaded

I haven't found any information regarding this error in this group nor
on google.

Hi Lennart

Thanks for testing,
can you try insmodding the driver with log_level=0x08 ?

The device is not created 'coz sensor probing failed & program exited.

Don't bother I already found the problem with the given information. I'm
working on it - patch is on its way.

But that instance made me think about our default log_level. In my
opinion the driver should output as few things as possible in it's
default state. That's why I already have a patch in my local repo which
reclassivies some stuff from INFO to DEBUG or ERROR.

Anyway - I think ERRORs should also be put out. Everything that's not
fatal is a warning or should be one so in the best case one precise
message is put out which tells us and the user where things went south.

Such a change would equal a default log_level=5.
Any other opinions?

Here is mostly harmless patch(0003) that adds so far missing devices to
the device-sensor translation table.

The other patches(0001) does the reclassification of some INFO messages
and change the default log_level.

The even more other patch(0002) hopes to fix the build problems users
with <=2.6.25 kernel may experience.

One "breaks nothing" should be enough to push this.

Thanks for the patch GWater, the module loads perfectly now and the
camera is working fine.

I had no errors while compiling the driver on my 2.6.27-kernel but I
applied the other patches as well.
Everything is working fine so far.

Additional informations on the device:
Brand: Vivanco IseeU Webcam
Extras: Integrated microphone

I understand the microphone is working, too?

(Audio is handled by a different driver and we always have to check that
we don't interfere with that.)

Actually this success message is enough for me to push the patches.

Yes the microphone is working when the webcam is turned on. I dont see
any problems there.
