The Commubox FXA291 by Endress+Hauser AG is a USB serial converter based on FT232B which is used to communicate with field devices. It enumerates using the FTDI vendor ID and a custom PID. usb 1-9: New USB device found, idVendor=0403, idProduct=e510, bcdDevice= 4.00 usb 1-9: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-9: Product: FXA291 usb 1-9: Manufacturer: Endress+Hauser usb 1-9: SerialNumber: 00000000 ftdi_sio 1-9:1.0: FTDI USB Serial Device converter detected usb 1-9: Detected FT232B usb 1-9: FTDI USB Serial Device converter now attached to ttyUSB0 Signed-off-by: Tim Pambor Cc: stable@vger.kernel.org Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman --- drivers/usb/serial/ftdi_sio.c | 2 ++ drivers/usb/serial/ftdi_sio_ids.h | 5 +++++ 2 files changed, 7 insertions(+) --- a/drivers/usb/serial/ftdi_sio.c +++ b/drivers/usb/serial/ftdi_sio.c @@ -1053,6 +1053,8 @@ static const struct usb_device_id id_tab { USB_DEVICE_INTERFACE_NUMBER(ALTERA_VID, ALTERA_UB3_602E_PID, 3) }, /* Abacus Electrics */ { USB_DEVICE(FTDI_VID, ABACUS_OPTICAL_PROBE_PID) }, + /* Endress+Hauser AG devices */ + { USB_DEVICE(FTDI_VID, FTDI_EH_FXA291_PID) }, { } /* Terminating entry */ }; --- a/drivers/usb/serial/ftdi_sio_ids.h +++ b/drivers/usb/serial/ftdi_sio_ids.h @@ -307,6 +307,11 @@ #define FTDI_ELV_UIO88_PID 0xFB5F /* USB-I/O Interface (UIO 88) */ /* + * Endress+Hauser AG product ids (FTDI_VID) + */ +#define FTDI_EH_FXA291_PID 0xE510 + +/* * EVER Eco Pro UPS (http://www.ever.com.pl/) */
