[sane-devel] reverse engineering advice.

2005-01-24 Thread Mbosowo I Sampson
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

[sane-devel] clean up usbsnoop logs

2004-10-19 Thread Mbosowo I Sampson
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

ading something about why its done this way. Was it in case multiple back ends were to be loaded? Something to do with unique names to avoid conflict. Thanks again for the speedy reply. Mboso On Sat, 4 Sep 2004, Bertrik Sikken wrote: > Mbosowo I Samps

[sane-devel] sane vs sanei_usb

2004-09-03 Thread Mbosowo I Sampson
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 someo

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

[sane-devel] writing hp scanjet 3970 backend

2004-08-27 Thread Mbosowo I Sampson
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
