Well, at least this output is normal - I get the same here for a 4-port USB-to-serial box, and it works, talking to two devices...
Try the stty program instead of setserial. It seems to better support these types of devices.

Hmm, bad connection with a too high baudrate? Have you tried with a lower setting?
I think 38400 is slow. With a regular null-modem cable this is no trouble. I can't think the USB would slow it down. I do not know how they implement handshake. I am guessing it is under software control. But that depends on the USB driver for this specific converter. I remember looking at the code to these types of drivers a while back and saw that there was quite a degree of variability in the completeness of the RS-232 emulation between different devices.
