The KUSB uses a Prolific chipset and it has problems when using slower baud rates and 2 stop bits. I experienced exactly the same behaviour with two different adapters (both using Prolific chipsets, though not bought from Elecraft) when I tested my K2 with KComm.
I believe the Keyspan uses an FTDI chipset which is somewhat better. Therefore the solution is probably going to be to use the Keyspan. I did find that the Prolific adapters sometimes work better by setting the serial port settings to 1 stop bit, but the baud rate of the KIO2 is fixed at 4800 so that can't be changed. ----- Julian, G4ILO.
