Hallo Luke,

thank you for your email.

usbcore is loaded already. I can add usbserial and ftdi_sio but it does not help. I noticed that lsusb does not show the device as it should do. under 3.16.4 it shows:

Bus 002 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

with 3.17.1 there is no entry at all. The usb port works fine with a flash device though. Furthermore, this issue only affects my i686 system. On a x86_64 system the device just works.
