Default USB/eth0 problem

I'm having trouble with my network card it fails to work when I plug in a
USB device. The USB device seems to function but restarting the network
doesn't start it working again.
I think this is a well known bug but is there a work around that anyone
knows about? If, for example, I compiled my network card into the
kernel instead of as a module would the bug still occur?
Can anyone give me a rough idea of what the problem actually is?

As far as I can tell, the phenomenon is such that /ifplugd/ gets
confused when you plug in a USB device and then brings the /eth*/
devices off-line.

The simplest workaround is to disable /ifplugd/ from running in the
default runlevel. If your machine is a server or a workstation, you
don't need /ifplugd/ anyway.

It's intended for laptops that aren't always connected to the Internet
or LAN.

Many thanks for the info but I'm not quite sure how to disable ifplugd.
It's not in the list when I try

rc-update show

so how do I disable it without breaking my system!

I'm not on Gentoo myself (yet), but there should normally be
configuration files for /ifplugd/ in */etc.*

There also are /man/ pages on the subject. My guess is that you should
edit the configuration files, with the instructions from the /man/
pages.
