Re: [Ftdi-usb-sio-devel] FTDI driver crash on 64-bit Ubuntu with Arduino

[Craig V. D. <cr...@yo...>]

Comment #10 in the following forum was helpful for getting my FTDI 2232C 
working again when I upgraded to Ubuntu 9.10.  It seems this fix is still not 
in the Ubuntu updates.  It might help with your problem.
