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.
