Hello,
I'm running FC1+Updates, with a self-compiled 2.4.22-1.2199.nptl kernel.
On bootup, the USB busses seem to deregister themselves and remove the relevant modules. A snippit from dmesg shows this ...
<snip> PCI: Setting latency timer of device 00:02.0 to 64 usb-ohci.c: USB OHCI at membase 0xf8a47000, IRQ 3 usb-ohci.c: usb-00:02.0, nVidia Corporation nForce2 USB Controller usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 3 ports detected PCI: Setting latency timer of device 00:02.1 to 64 usb-ohci.c: USB OHCI at membase 0xf8a49000, IRQ 7 usb-ohci.c: usb-00:02.1, nVidia Corporation nForce2 USB Controller (#2) usb.c: new USB bus registered, assigned bus number 2 hub.c: USB hub found hub.c: 3 ports detected PCI: Setting latency timer of device 00:02.2 to 64 ehci_hcd 00:02.2: nVidia Corporation nForce2 USB Controller ehci_hcd 00:02.2: irq 5, pci mem f8a51000 usb.c: new USB bus registered, assigned bus number 3 PCI: cache line size of 64 is not supported by device 00:02.2 ehci_hcd 00:02.2: USB 2.0 enabled, EHCI 1.00, driver 2003-Jun-19/2.4 hub.c: USB hub found hub.c: 6 ports detected usb.c: USB disconnect on device 00:02.0-0 address 1 usb.c: USB bus 1 deregistered usb.c: USB disconnect on device 00:02.1-0 address 1 usb.c: USB bus 2 deregistered ehci_hcd 00:02.2: remove state 3 usb.c: USB disconnect on device 00:02.2-0 address 1 usb.c: USB bus 3 deregistered <\snip>
BUT, if I wait for the system to finish booting and manually load usb-ohci by hand as root, the attached USB devices are loaded and any appropriate modules are loaded ...

Why the difference? How do I get the system to autodetect the attached devices and load the appropriate modules automagically?
usbcore is compiled into the kernel, but usb-ohci and ehci-hcd and device
drivers are modules if that makes any difference.
