Comment 9 for bug 14741

I believe that this is the same as Debian bug 302990:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=302990
Hopefully an upgrade to udev 0.56-2 will fix it (when that gets into Ubuntu)?

In the meantime, a workaround that works for me:

   # get a root shell

sudo bash -l

   # change the hotplug mechanism to /proc/sys/kernel/hotplug:

echo "/sbin/hotplug" > /proc/sys/kernel/hotplug

   # plug in your USB device now. wait a few seconds...

   # now revert your hotplug script to what it was before:

echo "/sbin/udevsend" > /proc/sys/kernel/hotplug

exit
