I dont want to get anyones hopes of of full fixes in 0.0.7, its a very hard problem (but have cleaned up a lot of related bugs in 0.0.7). However, we had the pleasure of talking it over a lot recently - and with a lot of users and developers of other products at maker faire - and have finally settled on a long term fix. Its a hardware fix, and a feature add, and were psyched. In the meantime if SerialUSB is really killing you, (and I hate to do this) please use the UART's with an FTDI for now - but with confidence that this problem will not plague this platform forever ;)</p> <p>from original comment:<br /> This would also allow us to add some JTAG based debugging features to Maple. It's a fairly large change and will add some cost to the board (~3.00??), but I think would be worth it just for my sanity, and also to apparent reliability to users. </p> http://forums.leaflabs.com/topic.php?id=217&page=2#post-1558 Mon, 04 Oct 2010 07:43:35 +0000 gbulmer 1558@http://forums.leaflabs.com/ <blockquote><p>Although what with it requiring extra hardware and being a potential source of mischief for an inexperienced user, I guess it's a little questionable whether it belongs in the IDE at all.</p></blockquote> <p>I mostly agree with you, but the Arduino also needs special hardware, so someone thought it worth while :-)</p> <p>A Maple isn't too bad, it needs a USB to serial cable/adapter/...<br /> After 1.0 is out, it might be worth writing the sketch to use one Maple to flash another (just using a Maple as the USB to serial converter).
