After I tried to do this and my Maple R6 is no longer<br /> recognized either. However the LED does the startup blinking and then turns off. I can get it to go<br /> into continuous download mode (LED stays on) but I can't use the IDE. There was an entry in the<br /> forums about 10 months ago about this but as far as I can tell there has been no fix posted.</p> <p>P.S. A useful command for seeing what USB devices are attached is lsusb. There are a few options to<br /> print out more or less information.

I'm using an old Maple board (I can't tell what version -- what are the recognizable features?) on ubuntu 11.10. When I plug the Maple in via USB, the blue light turns on and blink, signaling that it is getting power.</p> <p>However, it doesn't seem that my computer recognizes it at all! The 'Serial Port' dropdown in the IDE is greyed out and doesn't allow me to select an option. I've tried looking at my devices and I don't see anything under /dev/ like I normally do for an arduino.</p> <p>I can try uploading a program, but the IDE throws an error:</p> <p>"Reset via USB Serial Failed! Did you select the serial right serial port? Assuming the board is in perpetual bootloader mode and continuing to attempt dfu programming..."</p> <p>followed by</p> <p>"Couldn't find the DFU device: [1EAF:0003]"</p> <p>Any thoughts on what is causing this? </p>
