are the libftdi kernel modules installed?
Have you restarted after installing them?
Are you running ubuntu inside VirtualBox (I have read about a similar problem for this)?
I just installed the libftdi and restarted -- the moose stopped working again and needed to restart. I mean the mouse stopped working. As far as I know the moose is working just fine.
Earlier I removed brltty.
I am wondering if the mouse has an ftdi in it and is cause the lock ups.
I am still having trouble - I upgraded to ubuntu 10.04, I reinstalled the arduino package.
I also plugged in the arduino on a different usb bus from everything else.
At one time I managed to have it work long enough to upload a blinky program (one I wrote) and it worked. A minute later it lost the usb connection and then the mouse locked up.
I am running out of things to try. Can someone give me some tips on dealing with ftdi usb problems on linux??
Sounds like you have a hardware conflict of some sort. I have used Ubuntu 9.10 and now I am running Ubuntu 10.04 and I haven't had any issue at all.
Have you checked Ubuntu forum to see if anyone had experienced similar problems like yours? Without knowing the full hardware configuration, it would be pretty difficult to pinpoint the problem.
