Re: USB device notifier does not work

and none of them are shown or seen by the device notifier

I think that the device notifier plasmoid is for the mass storage devices ie. devices that need the "Safely Remove" option.

the USB webcam does not work, is this a bug

Has it been working with the Linux ?

It could be a Windows only webcam (i have one of those). Manufacturer doesn't provide Linux drivers or specifications, so nobody else can't make drivers.


You could:

google (your webcam name + linux/ubuntu)

or/and

what tells:

lsusb

dmesg | tail

after you plug in the webcam.


man lsusb

NAME
lsusb - list USB devices

SYNOPSIS
lsusb [ options ]

DESCRIPTION
lsusb is a utility for displaying information about USB buses in the system and the devices connected
to them.

man dmesg

NAME
dmesg - print or control the kernel ring buffer

SYNOPSIS
dmesg [ -c ] [ -n level ] [ -s bufsize ]

DESCRIPTION
dmesg is used to examine or control the kernel ring buffer.

The program helps users to print out their bootup messages. Instead of copying the messages by hand,
the user need only:
dmesg > boot.messages
and mail the boot.messages file to whoever can debug their problem.
