# the plusb network driver is a USB host-host cable based on the Prolific
# chip. It works a lot like the plip driver.  
#
# To get the plusb module to load automatically at boot, you will need to
# add the following lines to /etc/conf.modules:
#
# alias plusb0 plusb
#

cd /etc/sysconfig/network-scripts
