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).
