sounds like your usb or printer drivers are somehow conflicting with your drive. try uninstalling the usb and/or printer drivers and let windows re-aquire them. you could also check to see if their is an availiable update for them.
some other gereral things you might try......try disconecting the drive and then letting windows re-aquire it. you could also check for firmware updates. also, make sure that the " enable cd writting" box in the drive properties is checked.
