More details:
My system is SMP. Everything is a module.
I've only a printer attached. It was powered off and disconnected.
Hours later, I just plugged an USB cable in the Linux box but in the other outlet.
The cable is 9m long (one 3m cable plus 2x3m extension cables, probably
illegally long). At the other end there is _no_ device.
6 or 7 hours later, /var/log/messages starts to fill:

Tired of this, I unplugged the last 6m of the USB cable, leaving 3m in
the linux box. It had no effect. The next step was to get rid of the
modules involved:
modprobe -r printer
modprobe -r uhci
This immediately triggered the OOPS:

Jun 18 13:52:19 iapetus kernel: usb.c: USB bus 1 deregistered
