Howdy, Mac OSX 10.2.3 libusb-0.1.7 sane-backends snapshot from 1/11/03 Using scanimage (a command line front-end to sane) with libusb to my epson scanner fails during a bulk_read. The confusing thing to me is that it is not the first bulk_read which fails. I have caused sane to print out quite a bit of debug info and will append it below in-line. Should I expect libusb to be working on osx? I searched the archives and found http://sourceforge.net/mailarchive/message.php?msg_id=2704195 where Nathan Hjelm describes a problem he is working on and seems relevant to my situation. Any updates? Ricky Charlet Anyway here is the dump ============================= <<I had to delete the dump to get this message past the 40K limit of the list processor. I'll leave a bit of what I hope is relevant>> below is the output of `scanimage` with the environment vars SANE_DEBUG_EPSON=255 SANE_DEBUG_USB=255 SANE_DEBUG_SANEI_USB=255 <<snip>> [sanei_debug] Setting debug level of epson to 255.
