Hi
I am developing an application for the ATSAM30R. I want to use USB CDC (STDIO) for debugging purposes, unfortunately I cannot get it to work reliable.
If I use ASF4, I can get it to work fine, but if I use the ASF3 libraries (USB CDC STDIO) I cannot get it to work, Windows says that the device is unrecognized.
A really strange thing is that if I flash the ASF4 "hex" and after that, I start debugging the ASF3 project, the USB works, that is until I physically restart the device by removing power. I assume this has to do something with the cache either on the microcontroller or on Windows which would suggest a USB initialization error.
Here is my clock config:

In main I have:
system_init(); irq_initialize_vectors(); cpu_irq_enable(); sleepmgr_init(); stdio_usb_init(); stdio_usb_enable();
I would use ASF4 but unfortunately I need the MiWi libraries, which are only available in ASF3. Any hints on how to debug this issue?
