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

[Nicolas Martin]

Hi Jerry,

Are you running both Snoopypro and MF toolbox under the admin account ? 

The device to snoop should be the first one here in the list.

Never got this error before with Snoopypro, so difficult to tell. 
Did you try with to scan with the scan tool available in the control
panel (scanner icon) ?

Nicolas
