USB sd's do not attach

[George E Sollish <gsollish%autogear.net@localhost>]

Hi,

I have an IBM Z pro Intellistation running 5.0 amd64.  It's a fresh 
install and I'm loading lots of software, building from pkgsrc.  When I 
started usb sticks whould be detected and attach as sd's.  Now, several 
days and a few reboots later, usb sticks are recognized when inserted -- 
the vendor ids are correctly read and reported to dmesg -- but they don't 
attach, only a 'not configured' is reported.  The same usb sticks (four, 
from two manufacturers) are identified, attached and read/written by my 
FreeBSD and linux boxes, so it's not the sticks or the files on them.  I 
can also attach a wireless mouse to the usb ports being used, so it's not 
the ports.

It appears that something has removed the system's ability to recognize 
the sticks as sd devices.  Any idea what I did and how to repair it?

Thanks.
