Also check if other computers recognize the printer. ctmk June 19, 2010 7:17:58 PM if it is the front port, before u plug in ANYTHING (especially flash drive) check the connection to the m/b 1st. if it is the back port, try something else like a cheap mice will do. and did you have the driver installed?
