AFAICS from <a href="http://leaflabs.com/docs/bootloader.html" rel="nofollow">http://leaflabs.com/docs/bootloader.html</a> the Maple is either in ACM mode (ID 1eaf:0004) or DFU bootloader mode (ID 1eaf:0003). The DFU bootloader device is somewhere under /dev/bus/usb/X/Y (lsusb gives you the bus X and device Y number). Maybe your udev rules do not fire correctly on the DFU bootloader device? Or that it does not stay, and flips back to ACM mode? See also this thread, there seem to be some issues with the Maple udev rules on some Linux distributions: <a href="http://forums.leaflabs.com/topic.php?id=91" rel="nofollow">http://forums.leaflabs.com/topic.php?id=91</a> Koenraad on "Which groups in linux?" http://forums.leaflabs.com/topic.php?id=1279#post-10995 Thu, 31 May 2012 06:01:05 +0000 Koenraad 10995@http://forums.leaflabs.com/ Hi, Just to say I experience the same problem, with opensuse 12.1 32 bit. When I run as root, everything is fine. When running as normal user, I have to manually reset the device to program it. I modified the udev-rule to see if it is executed and it is. I think the problem is that /dev/ttyACMx is always owned by group dialout, although the udev-rule says it should be plugdev. Maybe some rule is executed later an that overrules the 45-maple.rules ?

I have the same issue, though I had already run the install udev rules script and running it now plus restarting udev and the IDE make no difference. Here's how my stuff looks. In the IDE on upload: Binary sketch size is reported above. Check it against a 108000 byte maximum. Loading via dfu-util Resetting to bootloader via DTR pulse Searching for DFU device [1EAF:0003]... Found it! Opening USB Device 0x1eaf:0x0003... Found Runtime: [0x1eaf:0x0003] devnum=0, cfg=0, intf=0, alt=1, name="UNDEFINED" Claiming USB DFU Interface... Cannot claim interface: could not claim interface 0: Operation not permitted We see no further progress from this point. Sometimes it gets stuck like this: Binary sketch size is reported above.

I had run the script with no errors when I set up the IDE, and attempted to restart udev, but for whatever reason that didn't work.

In the root of Maple IDE there is a script which does this - install-udev-rules.sh. fugalster on "Which groups in linux?" http://forums.leaflabs.com/topic.php?id=1279#post-7681 Mon, 16 Jan 2012 12:23:49 +0000 fugalster 7681@http://forums.leaflabs.com/ I'm running Ubuntu 11.10 32bit and having a bit of trouble with permissions. I am a member of root, sudoers, plugdev and dialout, but every time I try to upload the process gets stuck on the line: Claiming USB DFU Interface... However, when I run the ide as root (sudo ./maple-ide), I have no such problems. Apparently there's another group I need to belong to, but I don't know what it is.
