My brand new Imac G5 OSX10.3 is driving me mad as both the printer and scanner do not work properly with it. I have a Hp Deskjet 940C and a Canoscan N124OU both with updated drivers. The only way I can get them to work is if I unplug them from the usb port and then plug them back in - be it directly into the machine or into a powered usb hub. For the printer I then have to reselect it in the chooser. This is each time I restart the computer. I've been in contact with apple support and went through a number of things i.e resetting PRAM and NVRAM this has not solved the problem, in fact my scanner now won't work at all. Anyone got any ideas quick please before I get my sledgehammer out!
