    Hi,

    we've written a driver that does scsi over usb for the Microtek X6USB.
    After adding 0x99 to the supported scanners in sane1.0.2 I got this:

    root@ghanima:/usr/local/etc/sane.d > /usr/local/bin/scanimage -L

    [microtek2] sane_get_devices: local_only=0
    [microtek2] sane_get_devices: sd_list_freed
    [microtek2] sane_exit: MICROTEK2 says goodbye.

    The driver doesn't support scatter/gather. May that be the reason ?
