Enhance USB com port connection #29

Closed stenbergd closed 9 years ago

stenbergd commented 9 years ago

It seems the USB VCOM will only work if USB plugged in at FCB startup and then only as long as it is kept plugged in.

Investigate how to make this functionality work whenever the USB is connected.

Look at VCP_write (but avoid recursion?) Only send max 64 bytes (USB CDC FS PACKET SIZE) at each packet transmission

Not sure the problem is in the device, but rather the PC host. Do some testing.
