ULINK2 suddenly doesn't connect to PC anymore

 ULINK2 suddenly doesn't connect to PC anymore

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

same problem...

Please give us solution and tell to Keil to fix this serious bug.

ULINK2 is listed as Human Interface Device, see:
http://www.keil.com/support/docs/3266.htm.

Also let us know if the problem still exists when ULINK2 is not connected to target hardware.

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.
