Hmm. The only difference in my configuration appears to be
BATT_SUSPEND_USB=0
LM_AC_SUSPEND_USB0Does changing these to 0 affect anything?
I had an issue similar to OP's, above solution solved it for me.
Thx, SpleenThief

I'm at a loss, cannot reproduce, although it may have something to do with suspending, I'm running a laptop and this happened right after wake-up and inserting a USB mouse.

###############################################################################
#
# Configuration for Laptop Mode Tools
# -----------------------------------
#
# There is a "system" to the configuration setting names:
# CONTROL_something=0/1 Determines whether Laptop Mode Tools controls
# something
# LM_something=value Value of "something" when laptop mode is active
# NOLM_something=value Value of "something" when laptop mode is NOT
# active
# AC_something=value Value of "something" when the computer is running
# on AC power
# BATT_something=value Value of "something when the computer is running
# on battery power
#
# There can be combinations of LM_/NOLM_ and AC_/BATT_ prefixes, but the
# available prefixes are different for each setting. The available ones are
# documented in the manual page, laptop-mode.conf(8). If there is no LM_/
# NOLM_ in a setting name, then the value is used independently of laptop
# mode state, and similarly, if there is no AC_/BATT_, then the value is used
# independently of power state.
#
# Some options only work on ACPI systems. They are marked ACPI-ONLY.
#
# Note that this configuration file is a fragment of shell script: you
# can use all the features of the shell scripting language to achieve your
# desired configuration.
#
#
# Modules
# -------
#
# Laptop Mode Tools modules have separate configuration files, that can be
# found in /etc/laptop-mode/conf.d. Please look through these configuration
# files as well, there are many useful power saving tools in there!

# When to enable laptop mode
# --------------------------
#
# "Laptop mode" is the mode in which laptop mode tools makes the computer
# consume less power. This includes the kernel "laptop_mode" feature, which
# allows your hard drives to spin down, as well as various other settings which
# can be tweaked by laptop mode tools. You can enable or disable all of these
# settings using the CONTROL_... options further down in this config file.

# When to enable data loss sensitive features
# -------------------------------------------
#
# When data loss sensitive features are disabled, laptop mode tools acts as if
# laptop mode were disabled, for those features only.
#
# Data loss sensitive features include:
# - laptop_mode (i.e., delayed writes)
# - hard drive write cache
#
# All of the options that follow can be set to 0 in order to prevent laptop
# mode tools from using them to stop data loss sensitive features. Use this
# when you have a battery that reports the wrong information, that confuses
# laptop mode tools.
#
# Disabling data loss sensitive features is ACPI-ONLY, and it only works if
# your battery gives off frequent ACPI events to indicate a change in battery
# level.
#
# NOTE: If your battery does NOT give off battery events often enough, you can
# enable the battery-level-polling module to make this work. Look at the
# file /etc/laptop-mode/conf.d/battery-level-polling.conf for more information.

#
# If this is enabled, laptop mode tools will assume that SCSI drives are

and no kworker CPU hogging! I also tested the above with and without pcie_ports=compat. No difference, I plug in the mouse, the LED comes on and udevadm shows all add and remove events, yay!
Then I enabled a few more daemons, and the one that caused kworker to go to 100% was @laptop-mode-tools.
DAEMONS=(preload syslog-ng dbus network !netfs !@avahi-daemon !@avahi-dnsconfd @sshd @wicd @cups @alsa @samba @mpd @crond @bluetooth @acpid !@laptop-mode @cpufreqd)
]]>EDIT: delete link, I already referenced it earlier in the thread.
]]>EDIT: Aha. Last response: https://bugs.archlinux.org/task/22909
I'm using an HP DV5-2144ca.
]]>My thread is here: https://bbs.archlinux.org/viewtopic.php … 12#p897712
EDIT: My problem was solved by doing this:
# rm -rf /var/cache/pacman/pkg/kernel26-2.6.37.1-1-x86_64.pkg.tar.xz
# pacman -S kernel26
EDIT: Well, the problem is partially solved. It detects the first device plugged in, but none after that.
EDIT: My problem was having USB autosuspend disabled in laptop-mode-tools. I fixed this by changing "CONTROL_USB_AUTOSUSPEND" in /etc/laptop-mode/conf.d/usb-autosuspend.conf to 1 and having a long "AUTOSUSPEND_TIMEOUT".
