Hi,
While plugging a "Trust 150 Spacecam portable" into a usb2.0 port, this
is the

Any idea?

The video driver should create a symlink to the physical device, but
that's not the reason your camera is not working.

It does not seems like a hotplug problem. You may ask the author of the
driver. If you do that, it would be nice to ask him to link the
class_device to a physical device too.
Thanks,
Kay
