[8.0] hplip3/ugen printer problem

[Patrick Lamaiziere]

[FreeBSD 8.0/i386]

Hello,

I've got some troubles to print on an "all-in-one" printer HP
Photosmart C4680 which should work with the port printer/hplip3. The
printer prints half of a page, then ejects the page and prints the
rest or, depending of the resolution, repeats some parts.

It looks like there is a problem between hplip (hp is the cups backend)
and ugen but I don't know why.
I think the device disappears while printing, I see some 
"Unknown USB device: vendor 0x03f0 product 0x7411 bus uhub2" on the console.

The scanner works very well, there is also a card reader attached at umass/da0
but I removed umass from my kernel to be sure there is no conflict.

Any help will be appreciated, thanks.

Regards.
