We keep getting this issue.
The 450D implements a full serial/RS-232 level port. Make sure you cable supports RTS/CTS handshaking. You should have 5 wires on the cable, Pin 2 DATA OUT to computer, Pin 3 DATA IN from computer, Pin 5 GROUND, Pin 7 RTS, Pin 8 CTS.

As far as I know mine if a real PL2303 and CAT control works fine in Fldigi, wsjtx, and qsstv but I can't get Chirp to talk to it. It just times out and says something about expected 6 bytes got 0 or something like that. Nothing additional on console.

Thanks,
