What can I say? I run "# modprobe ohci_hcd", the cursor moves to the line below and that's it. No keys respond, mouse doesn't respond at all (no movement) - is this a kernel crash? I can't get USB working without ohci, as my motherboard USB ports need this driver. Previous experiences with USB: I have only tried to get USB working with gentoo with original kernel.org kernel sources 2.6.8.1 and 2.6.8. I tried first with 2.6.8.1 and I had some problems, found it to be hotplug wasn't up to date I think. Updated hotplug and it was fine, but I didn't have to load ohci-hcd manually, hotplug always did it for me. I seem to recall having tried loading ohci-hcd before updating hotplug, and my system crashing in the same way it does now. Once USB was working on 2.6.8.1, I wanted SCO support (bluetooth), so I downgraded to 2.6.8 (never used this kernel before) with a SCO patch. USB still worked perfectly, and so did SCO. Since then, I've reinstalled gentoo, and I can't seem to get hotplug to autoload the ohci module for me. Reproducible: Always Steps to Reproduce: 1.

I'm a bit confused. When you run "modprobe ohci-hcd", does your system hang? The only influence that hotplug could have on this that I can think of, is that hotplug may load some other modules first.
Yep, that's exactly what happens. What other modules may it load?
Dont know. I think you may need to "/etc/init.d/coldplug start" in order to get the old hotplug behaviour. Check "lsmod" before and after to see whats been loaded.
heh, I've not found anywhere that's told me to install coldplug. I just emerged coldplug, started it and wehey! Sorry for any waste of time. And thanks for the help.
Its still a bug if you require hot/coldplug in order to load the ohci module. Could you please do the lsmod test so that we have more of a clue
Well, before starting coldplug the only USB related modules I had loaded were usbcore. After, I have this: rob ~ # lsmod Module Size Used by rfcomm 35224 8 l2cap 24320 5 rfcomm nvidia 4822868 12 hci_usb 13568 5 bluetooth 44420 13 rfcomm,l2cap,hci_usb uhci_hcd 30352 0 ohci_hcd 20740 0 ehci_hcd 28420 0 snd_seq_midi 7584 0 snd_ens1371 22184 0 snd_rawmidi 22436 2 snd_seq_midi,snd_ens1371 snd_ac97_codec 67204 1 snd_ens1371 snd_seq_oss 34176 0 snd_seq_midi_event 7552 2 snd_seq_midi,snd_seq_oss snd_seq 54288 5 snd_seq_midi,snd_seq_oss,snd_seq_midi_event snd_seq_device 7816 4 snd_seq_midi,snd_rawmidi,snd_seq_oss,snd_seq snd_pcm_oss 51752 0 snd_pcm 90372 2 snd_ens1371,snd_pcm_oss snd_page_alloc 10120 1 snd_pcm snd_timer 24196 2 snd_seq,snd_pcm snd_mixer_oss 19200 1 snd_pcm_oss snd 51172 12 snd_seq_midi,snd_ens1371,snd_rawmidi,snd_ac97_codec,snd_seq_oss,snd_seq_midi_event,snd_seq,snd_seq_device,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss soundcore 8672 1 snd usbcore 105956 6 hci_usb,uhci_hcd,ohci_hcd,ehci_hcd rob ~ #
This is an upstream kernel bug..if you wish to report it, please go ahead (file a report at http://bugzilla.kernel.org). You should do some experimenting and figure out which modules need to be loaded before ohci-hcd for the system not to freeze. You'll obviously have to disable coldplug while running these test.
