Hi there,
Ive got a big problem with my TerraCam.
At time Im running Debian 2.2 with Kernel 2.2.16 and some patches
(ReiserFS,
USB, and the cpia-modules) - and the same problem exists on the
2.4pre5-kernel.
So, the problem: The webcam might be disconnected without any reason and
reconnected by the uhci-module. The light at the camp is for a moment
off/on.
Then the application, like xawtv gqcam and so on, tells me /dev/video
doesn't exists.
This happens every time in an 30second till 3min random intervall.
Here are the kernel-messages:

thats all.
does anybody could help me or even know this problem?
Me were told that the cam would be running fine.
If somebody need more information of my PC then contact me.
But I think I should say I have an VIA-mainboard (VIA USB-Hub or
something)
thanks!

Hi,
ich haette da ein kleines Problem mit meiner USB Webcam.
Im Moment fahre ich den Kernel 2.2.16 + ReiserFS-Patch + USB+Patch +
cpia-Module.
Aber das gleiche Problem taucht auch beim 2.4pre5er auf.
Nun, das Problem: Die Webcam scheint von den uhci-Modul immer wieder
"disconnectet"
zu werden. Warum auch immer. Das Laempchen der Kamera leuchtet kurz
aus/ein und dann
wars das auch schon mit jeglicher Anwendungen (xawtv, webcam, gqam), da
/dev/video demnach
nicht mehr existiert [bzw. nicht mehr zugegriffen kann].
Folgende Meldungen aus dem Kernel:

Und das wars auch schon mit Kamera. Hilft nur noch ein
entladen/wiederladen der
cpia-Module. Und das gleiche Problem faengt wieder von vorne an.
Weiss jemand mit was das zusammenhaengen koennte?
Ich hab eigentlich nur berichtet bekommen dass die Kamera bei anderen
Leuten
ohne Probleme laufen soll.
Wenn jemand mehr Infos ueber mein System braucht, kann ich diese gerne
zur
Verfuegung stellen. Ich moechte euch nicht noch weiter ellenlang mit
Messages
belaestigen und hoffe mal dass einer mir helfen kann, wenn nicht auch
mehrere.
MfG
robert
