On pd-list this morning...?

Well I'm interested, where did you post it to?

FIXED!!!

Please read my new post "Got Arduino UNO to work in Linux (Ubuntu)" if you need the fix.

I'll try this tomorrow, and i'll let you know if it works.

   I m pretty sure it's not related to the hardware, as it works
   perfectly fine in windows. I believe it has to do with the
   firmware.

       If you are plugging and unplugging the arduino it's possible
       the OS doesn't detect it properly. I know there were issues
       with the FTDI driver not reporting when the device had been
       removed, that caused Pd to hang.
       As long as your resistors are more than about 1 kOhm it
       should be OK.
       If you write ones to the input pins they will have internal
       pullup resistors enabled, so a switch that connects the pin
       to ground when it's on will work.
       And the pots should be wired like this:

       5V
       \
       /
       \<----Pin
       /
       \
       GND

       Anyway you say it works once it connects, so it's probably
       not the hardware, except possibly the cable/connectors.

           I don't get random dropouts once it's connected (I used
           it for 2 ours in
           Pd and it worked fine all the time), but it just doesn't
           appear (either
           in the Serial port menu of the IDE, or in the device
           list that comport
           outputs) randomly. Do you think that this could still be
           caused by
           something sucking up too much current? There's nothing
           special connected
           to the board : 2 pots, and 8 buttons (wired so that
           their rest position
           is High).
