Hi Pertti,
Glad that this solution works for you.
I found I also suffered this exact behaviour with my USB-to-serial adapter,
while the PC's onboard UART didn't suffer it. That is, the USB device would
lose characters from its transmit queue if inter-character spacing wasn't
used.
In the end the behaviour was proven by transmitting from the USB uart to the
motherboard UART via null-modem cable (ie, leaving my embedded application
out of it). It didn't have the problem in reverse though - the USB bridge
could receive at full speed, it just couldn't transmit.
I suppose is just goes to show that we're not always having to debug our own
embedded applications...

Yes, I tried it and it works. Since there is relatively
little data going from the PC to the Butterfly, that is
how it is probably going to remain as well ;-)
