ULINK2 suddenly doesn't connect to PC anymore

Werner Kuhn

Hello,

I'm working with the ULINK2 and MDK-ARM Version 3.04. I used the ULINK2 since January this year and it worked fine the whole time. Two days ago I wanted to continue my work and attached the ULINK2 to the MCB2300 board that I recieved from a colleague to download a hexfile. But it failed because the µVision IDE doesn't recognize the ULINK2 and stopped the process. I tried to find the reason an checked everything. But don't have any idea anymore what could be wrong.

So here the things I already checked to find the error:
1. I checked the cables -> OK
2. only the USB led is on after I attached the Ulink to PC
3. The Ulink isn't displayed in the windows device manager

Has anyone an idea what to do?

Thanks Rainer

    Hello,

    first thanks for your support.

    @Rheinhard Keil:
    The ULINK2 isn't displayed in the windows device-manager anymore, neither as USB device nor as Human Interface Device.

    The problem also occured if the ULINK2 isn't connected to the target hardware.

    As far as I know we send the ULINK2 already back to Keil to solve the issue.

    Thanks for your help.
