I already reported this as bug Bug #291906 but I didn't get any feedback
so here it is again:

I have Mustek gSmart 300 web cam. It worked fine under Ubuntu 8.04 with
the gspca drivers manually compiled and installed. When I plug the cam
it beeps showing that it is being recognized by the system. Then It
beeps again and I get a window with the following message:

Unable to mount Mustek Systems, Inc. gSmart 300
Error initializing camera: -60: Could not lock the device

After I click OK, there is an icon present at the desktop Mustek
Systems, Inc. gSmart 300. by clicking on the icon i can open the
location gphoto2://[usb:002,010]/. This probably gives me access to the
photo function of the webcam. I can copy pictures from this
directory(representing the cams internal memory), but I can't delete
them. If I try to delete a picture, I get this message:

Error while deleting.
There was an error deleting Image001.jpg.
Show more details->Not supported

The webcam function is not functioning completely. There is no
/dev/video created for it.

Description: Ubuntu 8.10
Release: 8.10

What confuses me most is the last message, [ 2092.207764] gspca:
disconnect complete, because  I am not disconnecting the webcam from my
computer .

I am also not sure if this is important but my Ubuntu 8.10 is an upgrade
from Ubuntu 8.04, so it is not a clean install. Also it might be
important for you to know that I have Pinacle PCTV Studio TV tuner card
installed on my computer. It uses BT878 driver. And it seams it is
broken too. It is listed in the Multimedia Systems selector but when I
test it the test doesn't show any errors, but there is no window showing
the picture from the tuner.

If you need more information please ask.
