If any of you are trying to use gutenprint with USB printers, it would
probably be useful to at least read this diff, and probably merge it
into FreeBSD.
When I started, I read diffs from FreeBSD's ulpt to NetBSD's, and
concluded that FreeBSD's was a lightly-modified (kernel infrastructure
issues) version of an older version of NetBSD's. I think a remerge is
in order. I'd be happy to answer questions if anyone works on this.

Module Name: src
Committed By: gdt
Date: Tue Jan 8 00:58:10 UTC 2008
Modified Files:
src/sys/dev/usb: ulpt.c
Log Message:
Support FIONBIO.
Support non-blocking reads from USB printers. With this, escputil can
query the printer model, and I can print a test page with gutenprint
5.1 and cups. Add many comments explaining why the support is not
quite right. (This change is quite a bit less invasive than a
"correct" fix, and thus more reasonable to pull up to netbsd-4.)
Rototill debugging, so that all DPRINTFN have a level, and so that the
message is printed if the debug level is >= the number in the source
code. Document debug level plan.
Fix bug where only one status change would be printed (by inspection,
not tested).
Document scheme for reading/discarding data when ulpt(4) is opened for
write only.
Delete dead code.
Plan and patch posted on tech-kern without objections.
