Does the lsusb command still function on a 3.2 kernel? At some point the
interface to usb devices in /proc changes and lsusb from el5 does
nothing. Copying lsusb.py from an el6 system to el5 does work and nearly
does the same things. Nearly.

I've just tested 3.10.5 on an el5 VM and that too passes the same tests
as above. Boots to runlevel 3, gives RTC errors but the patch that Phil
refers to does not work for me but I am not using the same .config so
perhaps I am missing the replacement rtc_*.ko modules.

By the way, while on that subject, cutting and pasting the rtc patch
from the web page does not work directly since the formatting on the
page neglects to indent the lines that don't start with + so patch
--dry-run says "malformed patch file". Similarly the link just above
that leads to a 404 so it can't be downloaded either.

Since 3.2 is being maintained as a long term kernel for Debian Wheezy,
it has support until at least 2016 where all the others expire sooner
than that - even 3.10 only lasts until 2015.
