KeyLargo/Intrepid USB (#3) > NEC Corporation USB > NEC Corporation USB (#2) Hrm... there is some problem in communication here. I asked you which controller out of the 3 OHCIs you have in this machine is the culprit, you give me a list of all of them but without PCI IDs ... From the archive, I think it was USB bus #4 no ? not sure which of these controllers it matches. The iBook G4 has actually 3 "Apple" OHCI's in KeyLargo/Intrepid but with 2 of them disabled by the firmware (not wired) plus one NEC USB2 controller (which contains 1 EHCI and 2 OHCIs) on the PCI bus. The code managing their sleep process is very different.
