Hello,
here are the scripts I use to analyze gl646 logs taken with usbsniff
1.8. It
takes a raw log and turn it into a file with higher level functions decoded,
which is much easier to understand. The decode() function used by
scripts/genesys_bulk_write_register.awk
scripts/genesys_bulk_write_register2.awk
scripts/genesys_read_register.awk
needs to be changed to decode gl841 registers. But the rest is OK. There are
still a few raw URB in the results, but they are understable (bulk reads of
data).
Once the scripts are tuned the process of adding support for GL841 is:
- use usbsniff to log scans with clearly identified parameters (dpi,
geometry, ...)
- decode the log with the scripts
- isolate portion of it and match them with high level action such as
head
parking, shading calibration etc ...
- change the corresponding functions in genesys_gl841.c to match the
decoded log.
- run scanimage to test with full debug log
- compare the scanimage log with the decoded log and fixe the
differences
you get.
- once a high level function is done, get to the next one.
I estimate it should take about 20 to 40 hours of work to finish the
gl841
backend.
Patches and questions are welcomed.
Regards,
Stef

Hello,
what I need to complete HP2400 support is usbsniff-1.8 logs- taken
under
windows- of clearly identified scans. Based on these data, I'd should be able
to tune the gl646 functions to run your scanner. However, since I don't have
acces to such a scanner, you (and others) will have to test the changes,
which will be a slow process. Hopefully the 2400 is close enough to the 2300
so it may not be that long.
Regards,
Stef
