Hi > Did you try sniff-usb 1.8 > See http://benoit.papillault.free.fr/usbsnoop/index.en.php
Great Idea!! This works perfectly and I can get all the transaction even during and after the previsualisation scan I put here the log (in ascii format this time) of the initialisation of the scanner : usbsnoop_init.log and of a session from initialisation to the and of the preview scan usbsnoop_preview.log.gz (careful, it is 5Mo compressed) I also try to play with sane-find scanner log_sane_find_scanner is the original output log_sane_find_scanner_modify is a bad hack where I remove the return 0; lines in check-usb-chip for the check_gl646 function Don't know if it can give information but it does not seems to say it can not read or write the registers.... If you have any idea or comments... Mike
