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

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

I just checked and determined that the kernel 2.6.32.1-9 currently in 
Ubuntu-10.04-Alpha1 can be complied and used in Kubuntu 9.10, at least it 
seems to run fine on my system.  My problem with ftdi_sio is solved in that 
kernel without special effort.
