I'm using the LPCXpresso development board with an LPC1769 MCU 4 and the LPCXpresso 4.1.0 Build 190, on Windows7 OS.

Every time I program, (or just connect to), the MCU via the USB debug Link, the system mouse (wireless, logitec) stops working; rebooting gets the system back to normal operation.

Is there some conflict between the dirvers?

It sounds like you may have shorted the USB power to ground.
The system notices the overload and shuts the USB subsystem down.
Generally a reboot fixes it.

Is this only when using LPC-Link?
I have a similar problem where my USB microscope camera stops working whenever I plu in any USB device (even a memory stick).
