<br>I'll try this tomorrow, and i'll let you know if it works.<br><font color="#888888">

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. <br><br><br><div class="gmail_quote"><div>2011/7/9 Martin Peach <span dir="ltr"><<a href="mailto:martin.peach@sympatico.ca" target="_blank">martin.peach@sympatico.ca</a>></span><br>

I know there were issues with the FTDI driver not reporting when the device had been removed, that caused Pd to hang.<br>
As long as your resistors are more than about 1 kOhm it should be OK.<br>
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.<br>
And the pots should be wired like this:<br>
<br>
5V<br>
\<br>
/<br>
\<----Pin<br>
/<br>
\<br>
GND<br>
<br>
Anyway you say it works once it connects, so it's probably not the hardware, except possibly the cable/connectors.<br><font color="#888888">

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