 I've updated the patch as I spotted errors in the original
patch.
 The url will still be http://www.ra
diotube.org/ulpt_poll.diff
 
 Fixes were:
 * Forgot to start transfer (in other words forgot to call
usbd_transfer)
 for the background read.
 * Panic in read callback at pipe abort.
 
 What I am interested to know about is how this works with
printers that
 actually do return any backchannel data, since my dumb
laser printer does=
 
 not return data at all.

Hi,

My new "ulpt.c" already supports ULPT polling.
Maybe you want to try that, and 
give me some feedback.

#
# How to install the new USB driver:
#

#
# First get all the sources 
# (you need /usr/ports/devel/subversion installed):
#

svn --username anonsvn --password anonsvn \
      checkout svn://svn.turbocat.net/i4b

#
# The following commands will
# install the driver on FreeBSD 6.x/7.x:
#

cd i4b/trunk/i4b/FreeBSD.usb
make S=../src package
make install

#
# Then build a new kernel (with modules)
#

--HPS
