Unknown USB device


The ASUS P7P55D mother board cannot recognize the USB port of DCP-135C printer from Brother. Do you have any suggestions ? Please help. Thank you.

  1. Can the same port recognize other things such as mice,flash drives?

    Also check if other computers recognize the printer.
  2. 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?
