I am close to assasinating my HP Photosmart C4280 in frustration.

1. This is an all-in-one device. (I did not try the scanner setup yet)

So far as I can determine, there is no reason to avoid uscanner in
the kernel --- uscanner does not/should not grab the scanner function
of your all-in-one.  It should then be possible to attach your single
function scanner with sane --- although it is sensible to get hplip up
without that complication first.

3. Machine is FreeBSD 7-stable/amd64.
4. hplip is 2.8.2

There is a ppd file for these series with the hplip distribution.

hpssd, cups started in the order needed. hp-setup detects the printer,
and then says 'Unable to create queue'. CUPS web interface actually adds
the printer, but then cannot print test page to it. cups user runs hpssd
(I tried root too).

/var/log/messages has:
Mar 25 23:57:56 omsk python: io/hpmud/musb.c 135: unable
get_string_descriptor -5: Input/output error Mar 25 23:57:56 omsk python:
io/hpmud/musb.c 1951: invalid serial id string ret=-5

Here is all relevant output:
A lot of stuff advertised here doesn't seem to be visible/existent to lynx.

devfd.rules looks right
check group --- have you added whoever is using the printer to group cups
                    (at least root and/or toor to print the test page)?
since you say you cannot print the test page, I assume you ran hp-setup
from a gui and can get into cups admin afterwards --- have you set the
printer you defined in hp-setup as the default printer in cups admin?

Is the printer ready (accepting jobs) according to cups admin?
yes, cups thinks the printer is up and  'ready', and accepts jobs for it.

if your failed test pages are showing up in the job queue, it may be
desirable to kill some of them in case you do something that does make it

Any help is appreciated. Thanks.
That's all I can think of off the top of my head.

I think the trouble is somewhere in usb or libusb: hp:/usb/Photosmart_C4200_series?serial=0 does not look right. The libusb exception seems to occur while trying to obtain the 'serial number'. Whatever that means -- is the device expected to provide it?

My understanding is that you didn't succeed to print from that printer. You have to get printing function first
before you can get scanning.
It is easily to use your device as only printer if you live ulpt driver inside the kernel but ugen driver is used to communicate and give you information as the ink level for instance. If you live ulpt driver you will not be able to scan libusb is used to communicate with the scanner. That is one of two ways that scanners talk to kernel.

Could you give me the output of

# /usr/local/libexec/cups/backend/hp (make sure you have the right path this is mine on OpenBSD 4.3 current)

If you get something like
direct hp "Unknown" HP printer (*HPLIP*)"
means that ugen driver cannot get VedorName and Product ID

Give me also outputs of



#hp-check -t

Out of curiosity what is the output of
