hotplug doesn't work quite right

[DrZoidberg]

I am trying to get hotplug to load the drivers for and configure the USB-Ethernet interface to my Zaurus PDA but it doesn't work right.

What I want hotplug to do is load the modules
usbcore, usb-uhci, and usbdnet automatically when I put the PDA on the cradle. (I already have a script working to bring up and configure the interface usb0.) Presently, I have to insmod the three modules by hand and then run the script.

First off, I'm confused about uhci vs usb-uhci. Hotplug insists on loading uhci, but I need usb-uhci. (Already tried uhci and it doesn't work!) How do I tell hotplug to load the module usb-uhci?

Also, is hotplug supposed to remove the modules it loads when I remove the USB device? Nothing happens when I take the PDA off the cradle or unplug the USB connector.
