hello everybody,

i run the cdc usb virtual com examples found at:


on my lpc11u24/301 microcontroller but after connecting the usb cable and visualizing correctly the virtual com i can't open the port with a serial data logger or any other software.

i imported the entire folder containing the cdc usb rom example and the build happens to be correct so it is the debugging.

what's wrong with my virtual com? i use windows xp and the driver provided by nxp support for letting the virtual com appears.

thank you very much for helping with this.

best regards
