# [PATCH] tiny race with devfs in printer
#
# USB printer bugfix
#
# looking through printer.c in preparation for shifting devfs
# support to usbcore I noticed that printer advertises a device
# through devfs before it can be opened.
# As devfs, or more precisely devfsd can be used to trigger actions
# this matters and is wrong.
