I have been having some problems with getting the USB port on my custom K60-based board, enumerating over VSB. Using the example virtual-com port as a starting point, I connected the USB to a laptop running Windows 7 and the laptop identifies the "device" as a HID - not a COM port. I have tried a different laptop, but the response is the same. I compiled the example and loaded it onto a TWRK60D100 board. The results were the same again.
Has anyone else had similar problems....??
