[sane-devel] My first test of SANE hp2400

[Bertie Coopersmith]

Thanks, Alexey for the PPA.

I tried both scanimage > file.pnp and scanimage > file.ppm.
In both cases it produced a greyscale image of good definition but my
source was in colour!

Also, both times on the return traverse it seemed to get stuck for a few
seconds while making a noise and then I have to switch off/on.
to get it recognized again as a usb device.     

Here is the output of lsusb -vv for my scanner. Alexey, you might find
it useful:

If you need more testing let me know. Colour would be nice!
