I have a problem with the ULINK installation. The first time I connected the ULINK adapter, I rejected the installation of the ULINK Device Driver. Now the driver no longer tries to install. Whenever I start debugging within µVision I get the message:
NO USB DEVICE FOUND
I have got this problem also with Windows XP Service Pack 2. What can be the reason?

This completes the installation of the ULINK driver and should recover your system (sorry that this is so complex, but it is a Microsoft procedure).

You should no longer have problems using ULINK from the Keil µVision3 Debugger.
