    Hi,my self tejas pawar.I have working on one project.in which i use ATmega8
    controller.There is simple circuit.The circuit is like that,five switches are
    connected to port pins of PORTC(pin1 to pin5).I continuously saning these five
    keys and according to whenever key press respected leter(A,B,C,D,E) send to hyper
    terminal.The connection between controller and PC usb port is made by using one market
    purchased kit ( usb to TTL converter kit )in which CP2102 IC is used.Now problem is
    that this circuit works properly with PC having configuration like Pentium,I3 processor ,
    working properly means then my device connected to PC USB port,is not disturbing to other
    connected devices to other USB port of PC ,devices like scanner,PS2 keyboard But when i
    connect this device to PC having configuration (celeron processor,1GB of RAM,1.2MHz frequency)
    the other connected devices(like scanner,PS2 keyboard) to other usb port are not able to connect
    or not working properly or not detected.why this type of problem arises and what is
    solution on it?whether problem in driver of kit or PC hardware.

    Does the Celeron PC (with driver loaded) recognise the converter properly?

    Go to the Device Manager and display the Ports (COM & LPT) and the Universal Serial Bus Controllers.

    Plug in the USB device and check that the CP2102 appears.
    Note which COM port is assigned to the CP2012.
    Use this COM port in Hyperterminal.

    I moved your thread to Computing and Networks since this is not Homework Help.
