Hello,

I have come across some USB Serial FTDI-based devices which are not automatically detected by ftdi_sio, as of Linux 2.6.17, because their Product IDs are not recognised by the driver.

The devices are:

1. AlphaMicro Components AMC-232USB01 (serial to USB converter cable)
- http://www.alphamicro.net/components/product~line~4~id~224.asp
- vendor ID 0x0403
- product ID 0xff00

2. Lawicel CANUSB (CAN bus to USB converter dongle)
- http://www.canusb.com/
- vendor ID 0x0403
- product ID 0xffa8

Below is the patch for drivers/usb/serial/ftdi_sio.{c,h} against Linux 2.6.17 which includes these Product IDs.
