Public bug reported:
When reconnecting a USB keyboard to my system, I got this stream of
messages in `/var/log/syslog`:
Mar 31 22:35:01 gatsby kernel: [442633.491562] usb 2-1.2: new low speed USB

A normal set of log messages for the same event looks like this:
Mar 31 16:36:44 gatsby kernel: [421175.156518] usb 2-1.2: new low speed USB
device using ehci_hcd and address 74
Mar 31 16:36:44 gatsby kernel: [421175.278006] input: Dell Dell USB
Keyboard as

Keyboard] on usb-0000:00:1d.0-1.2/input0
Since that error was logged, the system will no longer respond to the
connection of USB devices. There is no record of such events in either
`/var/log/syslog` or via `dmesg`.
I'm running 10.10 on an Acer Aspire 5742 laptop. It may be relevant
that both my HECI controller and SMBus show up as `UNCLAIMED` in the
output from `lshw`. They are both listed as being `/^\s*product: 5
Series/3400 Series Chipset (HECI|SMBus) Controller/`.
I'm booting with the `acpi_osi=` kernel argument.
This, or a different problem resulting in USB devices not being
detected, has happened once before, on 2011-03-12. I rebooted in order
to be able to use newly connected USB devices.
When the previous event occurred, I was not using the acpi_osi= kernel
parameter.
I was using the kernel package `linux-image-generic 2.6.35.27.35` (or
possibly an earlier one, depending on when/if I rebooted) at that point;
I have since upgraded to `linux-image-2.6.35-28-generic 2.6.35-28.49`.
Since my last reboot I have plugged and unplugged numerous USB devices
multiple times without any issues. Note the address `79` on the above
syslog messages.
I tried
$ sudo modprobe -r usbhid ; sudo modprobe usbhid
This logged the following to `/var/log/syslog`
Apr 1 00:41:10 gatsby kernel: [450189.768916] usbcore: deregistering
interface driver usbhid
Apr 1 00:41:10 gatsby kernel: [450189.768960] usbcore: deregistering

interface driver usbhid
Apr 1 00:41:10 gatsby kernel: [450189.823250] usbhid: USB HID core driver
but otherwise had no effect: newly-connected USB devices still do not
work, nor are any syslog messages generated in response to their
connection.
I tried connecting devices to two different USB ports on different sides
of the machine, both to the same non-effect.
