I did _not_ say that the USB warning was related to the wireless.
I've not noticed the USB error before.  I'm just reporting what I
occurred during the boot.

I too am currently running the ipw3945 v1.2.1 with the .20 kernel.   I
was just attempting to use the supplied iwl3945 driver in hopes of
getting suspend/resume working, which doesn't work.

NetworkManager works pretty consistently for me and makes things
easier.  I've written and modified the network scripts in the past so
you're not talking to a total noob.

This was just a report of things that weren't working after a cursory
glance.  I'm more concerned by the fact that my hard drive speed has
dropped rather than by the USB or the wireless issues.  I'm usually
working at a docking station so I don't have to worry about the
wireless.   The machine is unusable with the hard drive speed at <
2MB/sec.  The boot takes forever and the software that I'm working on
would take all day to compile.
