README
------------------------------------------------------------------------------
current status:
f1: frootloop3 gets corrupt data in rx path, _after_ serial rx,
but the usb in packets (wireshark) show the corruption. (LA on serial lines is clean)
f4: frootloop3 tests clean
=> suspect libopecm3 usb bug?
This implements a USB CDC-ACM device, connected to USART2 (PA2-tx/PA3-rx)
An interrupt driven tx ring buffer is used for usb->serial, and a similar
interrupt driven rx ring buffer is used for serial->usb.
