BlinkyPendant not recognized by dfu

Penth

I'm trying to hook up an program my blikypendant for the first time, using the code in commit 3e3f490 under Ubuntu 14.10. The device comes up as 1209:8888 if plugged in in standard mode, or 1209:8889 if plugged in in bootloader mode by pressing the select button, but dfu-util cannot open it in either case. The current firmware is the one loaded for the Open Hardware Summit.

 ~/git/BlinkyPendant/firmware$ make install 
 dfu-util -d 1209 -D pendant-firmware.dfu
 dfu-util 0.8

Also note that there's a typo in animation.cpp where '#include "Animation.h"' should be '#include "animation.h"' in order to prevent a file not found error on case-sensitive systems.

Hmm, firing up the linux box now to try and repeat this. Will fix that case issue too, OS X handles those things poorly.

Aha- try running it with root permission:
sudo make install

You could also make a rule for it in udev to give userspace permission for it (and filter on the above VID/PID pairs).

Doh, I should have thought of sudo. I'm in the dialout group and didn't have these problems with arduino, so I got lazy. dfu must have other ways of doing things.
