Subject: no USB keyboard in 3.5-rc1 and later

Here's hoping it's something simple.  Attached USB devices fail to
initialize/work for kernel version 3.5-rc1 and later (up through
3.5-rc4).  From what I can tell from the dmesg output (attached),
there used to be an "input" or "generic-usb" message that appeared
for each device following detection -- showing the sysfs path to the
device.

For the dmesg output excerpted below, I've left out the USB hub
detection/initialization messages.  The system *does* have a USB 3.0 hub
with nothing currently attached to it, just in case the presence of 3.0
hardware is an issue.

The relevant 3.4 boot time messages look like this:

Thanks in advance for any assistance in figuring out what's going on
here.
