So, multiple adaptors are clearly working here. Serial(port='/dev/ttyUSB1', baudrate=19200, bytesize=8, parity='N', stopbits=1, timeout=None, xonxoff=False, rtscts=False, I can link the two serial ports with a crossover cable and use screen to access them, via 'screen /dev/ttyUSB0 9600,cs8' and 'screen /dev/ttyUSB1 9600,cs8', and then whatever I type in one screen window appears in the other. Serial(port='/dev/ttyUSB1', baudrate=19200, bytesize=8, parity='N', stopbits=1, timeout=None, xonxoff=False, rtscts=False, dsrdtr=False)] [Serial(port='/dev/ttyUSB0', baudrate=19200, bytesize=8, parity='N', stopbits=1, timeout=None, xonxoff=False, rtscts=False, dsrdtr=False), usb 1-1.3.4: pl2303 converter now attached to ttyUSB1 usb 1-1.3.4: Manufacturer: Prolific Technology Inc. usb 1-1.3.4: Product: USB-Serial Controller usb 1-1.3.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.3.4: New USB device found, idVendor=067b, idProduct=2303

Oh, you can use minicom to talk to your device serially too, if it accepts ASCII characters. My problem at the moment is sometimes whilst the Pi is running (it's on 24x7) ttyUSB1 will dissappear & USB2 will appear. I start this via init.d & have a web front end I'm working on to create the ip file & read the op file. It reads one line of text from an input file (ip) and sends the text to the device then reads any response & puts it in the output (op) file. # let's wait one second before reading output (let's give device time to answer) # configure the serial connections (the parameters differs on the device you are connecting to)
