Hello,
I have tried to use your awk scripts on the windows usb logs. There seems to
be a missing file from your tarball, here's what I get when I run decode.sh:
reformatting data ...
compacting URBs ...
sorting ...
depacking ...
parsing ...
awk: fatal: can't open source file `parse1.awk' for reading (No such file or
directory)
executing motor2.awk...
executing genesys_get_status.awk...
executing testR70.awk...
executing genesys_fe_write_data.awk...
executing genesys_set_buffer_address.awk...
executing genesys_set_buffer_address2.awk...
executing genesys_read_feed_steps.awk...
executing genesys_bulk_write_data.awk...
executing genesys_bulk_write_next.awk...
executing genesys_bulk_read_data.awk...
executing genesys_bulk_read_next.awk...
executing genesys_bulk_write_register2.awk...
executing genesys_bulk_write_register.awk...
executing genesys_read_register.awk...
Needless to say I get an empty output file.
regards,
Carlos.

Hi Martin,
I started having a look at this several weeks ago but had to put
everything aside preparing for Easter. I had the same problem with
SnoopyPro and wasn't able to spend time on tracking down a more helpful
alternative program. Maybe over the coming weekend :-)
I've presently got my Canon LiDE 500F running on a dual-boot
win98/RedHat9 box (networked to a couple of other linux machines)
I'll let you know what progress I make :-)
Jeff
