finally got TX working without any delay, there is some weird timing involved in what happens when the line state is toggled (host port disconnected) and theres still data waiting to go out, this will hang any while(txCount != 0) calls. similarly, sending data without checking txCount != 0 will hard fault the chip. This is all handled now by usbSendBytes, which returns -1 for unconnected, and 0 for simply 'waiting to send'
