in /proc/bus/usb you should have a file called devices. Doing 'cat
/proc/bus/usb/devices' should at the very least contain details of your
root hub (your mobo)

I have not had extensive experience with hotplug (it didn't work on my
machine. Repeated lockups when plugging things in. Changed to usbmgr and
all is well :(  )

IIRC the stuff in /proc/bus/usb is all to do with the usbdevfs setup. In
your kernel config, enable CONFIG_USB_DEVICEFS.

Also, you need at least a UHCI or OHCI driver. I would try
CONFIG_USB_UHCI first, followed by CONFIG_USB_UHCI_ALT, and finally
CONFIG_USB_OHCI (just build them all as modules)

This is the USB bit of my kernel config:

CONFIG_USB=m
CONFIG_USB_DEVICEFS=y
CONFIG_USB_UHCI=m
CONFIG_USB_UHCI_ALT=m
CONFIG_USB_OHCI=m
CONFIG_USB_BLUETOOTH=m
CONFIG_USB_STORAGE=m
CONFIG_USB_ACM=m
CONFIG_USB_PRINTER=m
CONFIG_USB_HID=m
CONFIG_USB_KBD=m
CONFIG_USB_MOUSE=m

This is using kernel 2.2.19, with the USB patches, but it is 95% similar
to the 2.4.12 one (and so I presume the 2.4.17 one :)

This works perfectly with usbmgr, if not hotplug :)
