[sane-devel] Canon imageCLASS MF5770 does not work with sane

[Jerry Zhang]

Hi Nico,

Thanks for your reply.

I tried snoopypro.exe v0.22 (followed this link:
http://roback.cc/projects/iRiver/howto/snoopypro/) but it won't
capture anything for me.

The snoopypro's USB Devices window lists 4 devices of MF5770

USB\Vid_04a9&Pid_265f&Rev_0000&MI_00,USB\Vid_04a9&Pid_265f&MI_00
 Canon MF5770
USB\Vid_04a9&Pid_265f&Rev_0000&MI_01,USB\Vid_04a9&Pid_265f&MI_01
 USB Printing Support
USB\Vid_04a9&Pid_265f&Rev_0000&MI_02,USB\Vid_04a9&Pid_265f&MI_02
 USB Printing Support
USB\Vid_04a9&Pid_265f&Rev_0000,USB\Vid_04a9&Pid_265f
           USB Composite Device

If I "install and restart" snoopypro driver on the first device
(MI_00) or the 4th device (USB Composite Device), my scanner
application (MF Toolbox) complains about "Cannot communicate with
scanner" and USBLog window shows nothing.

If I "install and restart" on the other 2 devices (MI_01 and MI_02),
MF Toolbox does scan but the USBLog is still empty.

Any suggestion?

Thanks,

Jerry
