So this should be working then. In the logs you sent I didn't see any
information from the hotplug scripts. I don't have a device with me right
now to show you what it normally outputs.

I don't think it is too much to ask everyone to read the FAQ before asking
questions.

Yes, it would help a lot.

The fact that there is no driver after "Driver=" tells you that you USB
system is working and that there is no suitable driver (some devices may
work if you force a driver to bind to them, like generic serial).

Did you do this while a uhci driver was already loaded? As it hasn't
succeded and you can see the contents of /proc/bus/usb/devices I suspect
so. On my system I have;
[pb-d-137-138-42-247] ~ > grep usb /etc/modules.conf
alias usb-controller usb-uhci
so that RH7.2 loads this automatically at boot time, although perhaps
hotplug would do it automatically as a PCI hotplug.
