I compiled and booted 2.4.23-pre5 this morning, and my USB doesn't work. 
  The devices I have are a HP psc2110xi and a Logitech Cordless Optical 
Mouse (Logitech Click! Plus).
My USB does work under 2.4.23-pre4.

I have attached my config and boot messages. I enabled ACPI and USB 
debugging.

Thank you
David
