Description Brian G. Anderson 2005-12-05 04:32:22 UTC
Description of problem:
I have an IBM T42p.  With previous kernels I have been able to put the machine
to sleep and then restore it with no adverse affects to the recognition of USB
devices.  With the latest kernel upgrade, after waking the machine no USB
devices will be recognized.  

For example, after a restart, when I plug in a USB mouse I would get the
following messages:
Dec  4 20:22:30 bartali kernel: usb 3-1: new low speed USB device using uhci_hcd
and address 2
Dec  4 20:22:30 bartali kernel: input: USB HID v1.00 Mouse [Cypress Sem PS2/USB
Browser Combo Mouse] on usb-0000:00:1d.1-1
Dec  4 20:22:30 bartali hal.hotplug[3320]: DEVPATH is not set (subsystem input)
Dec  4 20:22:30 bartali ntpd[2511]: synchronized to LOCAL(0), stratum 10
Dec  4 20:22:30 bartali ntpd[2511]: kernel time sync disabled 0041
Dec  4 20:22:33 bartali kernel: usb 3-1: USB disconnect, address 2
Dec  4 20:22:33 bartali hal.hotplug[3368]: DEVPATH is not set (subsystem input)


After sleep and then wake, the kernel issues the following message, when I plug
in the mouse again:
Dec  4 20:23:21 bartali kernel: hub 3-0:1.0: over-current change on port 2
Dec  4 20:23:21 bartali kernel: hub 3-0:1.0: over-current change on port 1
Dec  4 20:23:21 bartali kernel: hub 3-0:1.0: over-current change on port 2
Dec  4 20:23:22 bartali kernel: hub 3-0:1.0: over-current change on port 1

I get the same messages with USB disks.  Also Bluetooth devices, whic appear as
a USB devices, no longer appear.

Version-Release number of selected component (if applicable):
2.6.14-1.1644_FC4


How reproducible:

Steps to Reproduce:
1. put machine to sleep

This kernel fixes the problems I've had with USB and bluetooth.  After wakeup
bluetooth and usb is operational.  Thanks.
