Thanks for digging into this. I'll go ahead and just add a note tonight about 'usblp' module. Is there any additional info that needs to be added here beyond the module being blacklisted (or not built is actually what I had planned on putting into the book)? It'll be a couple of weeks more before I can test any udev rules or such (I can't move my printer to my dev machine right now, not to mention that I'm plugging away on a fresh 6.7), so if a patch would be more appropriate, I'll be more than happy to apply if a note is insufficient. -- DJ Lucas -- This message has been scanned for viruses and dangerous content, and is believed to be clean. -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
