 Well, it looks like it's there. I have sorta set it up;

[root at bartender hotplug]# cat /etc/hotplug/usermap 
usbcam               0x0000      0x04a9   0x304e    0x0001       0x0000
0x00         0x00            0x00            0x00            0x00
0x00               0x00000000

 Where the USB ID of my camera is 04A9/304E. usbcam is a script in
/etc/hotplug/usb/usbcam that's supposed to be run when it's plugged in.
All good & proper. But, /sbin/hotplug isn't run by the kernel, when it's
supposed to be. Which is the kernel side bit that starts it all off. And
that ain't happening.
