I needed to remove just the ehci-hcd module. Please note that this is
with a 2.4 kernel. In particular, this is SuSE 8.1, with a
self-compiled 2.4.27 kernel. I added:

      # Unload USB module that doesn't resume properly.
      # Stop hotplug system.
      rchotplug stop
      modprobe -r -s ehci-hcd

to the suspend case in /usr/sbin/apmd_proxa, and

      # Reactivate USB hotplug system. This should also reload
      # the ehci-hcd module. Well, sometimes it doesn't -- but maybe
      # the module did not get unloaded on suspend? To make sure, we
      # check if it's there and unload it anyhow.
      if lsmod | grep '^ehci-hcd' >/dev/null ; then
         modprobe -r -s ehci-hcd
      fi
      rchotplug restart >/dev/null

to the resume case. Then it worked.

Btw, when I plug in my USB mouse for the first time after booting, X
will not notice its arrival. Changing to a text console and back to X
triggers the recognition.

Cheers,
	Joachim
