I'm in the process of sifting through USBSnoop generated logs for the HP
3970, trying to decipher what's going on. I've hit a little bit of
a wall. Reading the code for the hp5400 driver along with the USBSnoop
logs posted at http://home.kabelfoon.nl/~bertrik/plugin_hp5470c.log
has really helped
I would like to post some usbsnoop logs to get some feedback, but the
files are huge. I was wondering what scripts people used to strip the big
bulk transfers from their logs. I have a web account that only gives me
20mb of space, but my average log size is about 30Megs.
I'm trying to reverse engineering the hp3970 scanjet. I have a couple of
snooped logs I wanted some help deciphering. I didn't
want to append or attach multi-megabyte files to the list, so I set up a
source forge account to upload the snooped usb logs. It works but it
doesn't keep the formattin

After reading reams of documentation, I think I have a grasp on how the
USB protocol works. I started snooping the usb traffic of my hp scanjet
3970 so I can start writing the backend for it. I have a couple of
questions...
With Snoopy Pro it seems to stop logging information once the actual sc

Thanks again for the speedy reply.

Have a question about the functionality of sane_open vs sanei_usb_open
(and other parallel functions). As I understand it, sanei_usb_open opens
up a connection to send and receive usb specific information. What I'm
confused about is if there is any overlap with operation sane_open. Could

I haven't started writing the driver yet. I'm still in research and
discovery mode (snooping the windows driver protocol). I only got the
scanner last week so I'm pretty new to sane. I'll post updates on the list
once I've made some headway. It might take some time so don't hold your
breath :-)
I'm interested in writing a back end for the 3970. I've been reading
specs, looking at other back ends, trying to get familiar with sane,
etc... Its all a little daunting. I feel as though I know more than I did
a few days ago, but not nearly enough to even begin to know where to
start. I think
I was just curious as to whether or not someone is working on the hp 3970
backend. If not, I wanted to begin writing it. There was one post a few
months ago about this same backend, but I've confirmed that that person is
not working on it. I have programing experience, but this will be my first
