Subject: [PATCH] ftdi_sio driver - new PIDs

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.

Signed-off-by: Jonathan Davies <jjd27@....ac.uk>
