[REGRESSION] usb devices don't wake up the system

[Maxim Levitsky <maximlevitsky@gmail.com>]

Hi,


This is my desktop, and I don't use it much.
I updated the kernel from 2.6.33 to 2.6.35-rc3, and my usb mouse (usb
1.1 of course) doesn't wake the system anymore.

I used (and still do) to enable wakeup via /proc/acpi/wakeup.


maxim@MAIN:~$ cat bin/system/wake_all 
#! /bin/bash

echo "UHC1" > /proc/acpi/wakeup		# ICH8 UHCI1
echo "UHC2" > /proc/acpi/wakeup		# ICH8 UHCI2
echo "UHC3" > /proc/acpi/wakeup		# ICH8 UHCI3
echo "UHC4" > /proc/acpi/wakeup		# ICH8 UHCI4
echo "UHC5" > /proc/acpi/wakeup		# ICH8 UHCI5

echo "ILAN" > /proc/acpi/wakeup		# ICH8 internal (lan/azal//EHCI)
echo "P32" >  /proc/acpi/wakeup 	# ICH8 external (PCI/PCI express)
echo "UAR1" > /proc/acpi/wakeup		# SUPERIO (UART/Sleep button)



I checked, and it looks like power/wakeup attributes are enabled:

root@MAIN:/sys/bus/pci/devices/0000:00:1d.0# cat power/wakeup 
enabled
root@MAIN:/sys/bus/pci/devices/0000:00:1d.0# cd usb5/
root@MAIN:/sys/bus/pci/devices/0000:00:1d.0/usb5# cat power/wakeup 
enabled
root@MAIN:/sys/bus/pci/devices/0000:00:1d.0/usb5# cd 5-1/
root@MAIN:/sys/bus/pci/devices/0000:00:1d.0/usb5/5-1# cat power/wakeup 
enabled <--- this I set manually to enabled, didn't help

I don't have much time now for testing, but will try my best to do so.
