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. -- Public PGP: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x56FAE049 Q: What is the difference between Texas and yogurt?

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 -- Rev.
