If you were to continue looking farther down in the log, you would find

That makes sense - that is indeed what happens when it DOES work (i.e.
with 2.6.15), but the fact is that they don't come back in 2.6.16. I
will try building ehci-hcd in and see what happens.

Around 2.6.13, I noticed that EHCI stopped working after a suspend/resume
(to/from RAM) cycle.  So I updated my suspend script to unload/reload EHCI
each time, which fixed the problem for me.  My script still does that.

Dunno if it's fixed in mainline or not.
Does unloading/reloading EHCI help you?

  rmmod ehci_hcd ; modprobe ehci_hcd
