    Does the UC00B work without the adapter (pluging it directly into the computer's USB port)?

    Why do you need an USB A / USB B adapter at all?

    Yes, the UC00B work fine. Problem occurs at my DIY circuit. I need that because the UC00B is so short and very inconvenient. I need an extension so that I can use it better :)

    Assuming you have the power connection correct, my next guess is that you have the data+ and data- connections swapped over.

    Just use an USB type A extension cord.
    Avoid the hassle with a PCB.

    Harald, I dont have the A type extension.

    @steve,
    swapped over means I misconnect them ? I dont think so

    what weird is that, I just solder the USB B type female to a stripboard. Then I plug in the USB B male, then it gave me that error message. LOL

    I thought I made a mistake once, but I was wrong.

    See this. ! So I dont think it involve the misconnect of D+ and D-. Cause I just solder them

    You just solder the connector to a PCB but no electronics?

    Can you show us (or better yet: link to) data sheets for the type A and type B connectors? I mean the ones you use, not just general information.

    The connections seem to be o.k..
    Try to locate the USB device in the Windows device manager and delete it there. You may have to install a suitable driver for the UCB001 board before connecting it to the PCB.

    Erm , I am not connecting UC00B. When I plug in the USB B male from printer cable to USB B female from DIY converter, it already gave me the error . I didnt even conenct a device to the USB A type female on the DIY converter. I think does not involve the driver or what

    Check to make sure you haven't accidentally shorted one of the data leads to ground, or VCC or even shorted VCC to ground.

    Do you get the error if you only plu in the cable to the PC, nothing on th eother end of the cable (no PCB at all)?

    Then there is an error on your PCB, possibly a short. Verify with an Ohmmeter that the plug on the PCB has no shorts.
