[Ftdi-usb-sio-devel] How to make a module ftdi_sio run two devices on different VID and PID

[Pawel K. <pkr...@sl...>]

Hi,

would you like to be so kind and give some advice for my problem. I have 
a device (passport reader
which contains of 2 device in there OCR optical reader and RFID chip 
reader). I'd like to map both
devices (one USB cable connector) to my linux system. Both of them run 
on "ftdi_sio" kernel module,
but there is the problem. I have to install the module like this:
  # modprobe ftdi_sio
there is no mapping for any ttyUSB*

if I run:
  # modprobe ftdi_sio vendor=0x1781 product=0x09af
there is OK, a have a mapping to serial port /dev/ttyUSB0 of one of the 
device (OCR part)
but I am unable to map the second (RFID part) to /dev/ttyUSB1.

Of course, if I install the module:
  # modprobe ftdi_sio vendor=0x0403 product=0xdd20
I have RFID device mapped to the /dev/ttyUSB0

My question is if there is any method to run both devices by the module 
"ftdi_sio".

I tried to change a name of that module to for example "ftdi_abc" and run:
  # modprobe ftdi_sio vendor=0x1781 product=0x09af
  # modprobe ftdi_abc vendor=0x0403 product=0xdd20
and it seems to be OK, but for me it's very odd way.

Here is the "devices" file from "proc" for my Device:
