I have a wee problem. My printer WAS working fine. It's an HP All-in-one PSC-1210. I got a new printer (HP colour laster 2600n, network attached), got that working, then went to try & use the 1210.... No go...
So I investigated a bit... And it looks like the USB functionality is a bit
broken on my Linux box...
OK. dmesg shows the printer being attached.

So why? What's happening? If I specify a diofferent device to lsusb -D it
tries the link, gets EINVAL & then does an fstat... But just seems to give up
on the printer... Why? Any ideas? is my printer haunted?
Oh yeah... The printer, cable etc all work fine on a Windoze machine... Go
figure.
