Like the ATmega32u4s Arduino bootloader that allows the uC to emulate a virtual UART over usb connection while at the same time maintaining a USB device connection is it possible with the 11u24.35 too? I'm talking about a custom board here and not the mbed dev. board with the interface chip that is used for usb comm. and uart on the lpc11u24/35 is free!

Yes thanks I got it some days back but would there be drastic problems if I use the USBdevice class like the HID keyboard or mouse along with the USB serial? can I normally use the methods from USBserial class and the USBdevice HID class without any clash of the titans?

Using them at the same time is an issue, they will not nicely cooperate.
