hotplug: problems with cold-plugging
Hi!
I've used usbmgr to manage my USB devices till now and everthing worked
fine. But I read that for 2.4 kernels hotplug is the suggested way to
go and not usbmgr.
So I now tried to set up hotplug.
The hot-plugging itself works fine. But hotplug doesn't detect what is
already plugged in at boot time. I have to unplug and replug the
devices in order to make hotplug load their drivers.
Can't this be done properly?
After booting with three USB devices attached (trackball, serial device
and floppy), I have those log messages in dmesg:
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb.c: deregistering driver usbdevfs

So, no driver has been loaded. Not even the trackball one, although I
have set X11_USBMICE_HACK=true in /etc/default/hotplug.usb! After
unplugging and replugging each device, I get the following messages
with dmesg:

So, why does it not work during booting and how can I make it work?
TIA.
