Unfortunately I was not given much time to read the USB 2.0 spec and hence was hoping to use the LPCUSB stack (like a black box) without having to understand it. I enabled the debug messages and indeed there seems to be some problem when my USB device is connected. Something about descriptor 0x600 not found, handle request failed. Any suggestions? If not, is there a open source/free USB analyser that you could recommend?
