Many thanks for the responses...& regrets I couldn't get back before now. My laptop is a Dell Inspiron
1525 with Windows Vista and my printer is multifunction, Canon MX390 series. It is USB-attached to my
laptop and working fine. I use this printer for the 3 months away from my home printer. Being away, I
don't have access to the disc for either the laptop or printer. All worked well last year for the 3 months,
but the problem began immediately when I connected the two devices 3 months ago. I've gone to the
Canon support site and installed the drivers called for. The Printer folder shows my Canon MX390 series
Printer/Fax "ready". The Device Manager lists both under "Printers". An obvious problem: under "Other
Devices" is listed "MX390 series" with a yellow!. Many times I've uninstalled it, but it returns after reboot.
Listed under "Universal Serial Bus (USB) Controllers" are: MX390 series, Universal Serial Bus (USB)
Controllers (7 listings), Unknown device (7 listings), USB Printing Support (2 listings). Without having
the disc with me, I saw the "motherboard" data in my BIOS (Dell OU990C Microprocesssor) & Chipset
Model GM965. I attempted to re-install from an online search and was informed they "exist already".
I would appreciate and welcome any help anyone can offer. Again, thanks!
