USB serial not working about f1rmware

[jonnor]

Need this for MicroFlo (a dataflow programming env I ported to radio), so I can live program it from host : )

I have tried to use CDC as well, with both the rad1o library code and NXP's library code for the NXP4330. In both cases I could not get it to work: The VCP device does not appear on my laptop and the code appears to wait forever on a call to vcom_connected().

Also in the testapp's cdc tester does not work at first use, it hangs as well. It does work when starting the testapp, selecting msc, stopping msc, and then starting cdc. So it looks like the msc code initialises something cdc needs as well..

@erikbos So when you run the msc code first, you see the serial device on laptop?

Yes, the usb device appears on my Mac. "screen /dev/tty.usbmodem-" connects to it and the cdc option in the demo app echos everything that I type back to me. Characters typed are echoed with bracket as the code is supposed to do, so it is not the local terminal doing the echoing.

FYI: as work around in my rad1o app code I added:

MSCenable();
MSCdisable();
CDCenable();

to toggle MSC mode on and immediately off, followed by calling CDCenable: that appears to reliable setup the rad1o's for CDC.
