I have a Canon mp287 printer and scanner, when I press the scan button I get an error saying 'cannot communicate with the scanner' (screenshot attached). I found a solution to this problem by disabling 'Enhanced host controller' under USB in device manager. (screenshot shot attached), but after I disable this enhanced host controller USB menu, it affects the whole performance of the transfer to EHDand pendrives (transfer speed of around 700kb/s,when it used to be around 30mbps for my External hard drive) .. ,.. Can anybody help me with an alternate solution..? There is no problem when I connect it to my laptop, works like a charm.. Lots of people have reported this problem but couldn't find a working solution yet.
