Problem with Dicimilla FTDI driver under linux

by ducksauz on Sat Nov 03, 2007 10:56 am

Ahoy hoy!

I just setup a new machine for dev work (my old one died after 5 yrs of faithful service) I'm having trouble with getting the FTDI USB/Serial interface to work. It seems to be recognized by the kernel, but then immediately disconnects.

Specs of the new box are as follows.

Athlon64 X2 3800+
1 GB Ram
Ubuntu 7.1 "Gutsy Gibbon"
Linux twofer 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux

Could the fact that I'm not running the AMD64 optimized dist be the problem?

Here's the applicable contents of /var/log/messages of me plugging in and unplugging it a few times.

It was late, I was tired.
I knew there was something I was missing.

Thanks a bunch!
