Sorry if this is unhelpful - this happened to me a few months back and I
_think_ what happened was my version of either avrdude, gcc or some other
part of the chain was incorrect. I was using OS X and homebrew and pretty
sure I solved it by uninstalling and reinstalling the correct versions of
the different software and dependencies.
Again, sorry if I'm remembering this incorrectly, but I'd check those
things out if I were you. Or verify that the commands being called are
pointed to the right versions of the binaries, if you have more than one
(PATH and stuff)

Hi,Vinney Cavallo <http://vinneycavallo.com/>
I'm having trouble uploading a modified firmware to my atreus. In normal
use, the atreus appears at:
/dev/usb/hiddev0
In bootloader mode it is not visible at all - diffing /dev/ before and
after shows no difference.
make upload USB=/dev/usb/hiddev0
does nothing - it just waits until I cancel
Repeating the make upload command as root I get the following:
.../keyboard/atreus make upload USB=/dev/usb/hiddev0
if [ -f /dev/usb/hiddev0 ] && [ ! -r /dev/usb/hiddev0 ]; then echo
"Warning: no read permission!"; fi; \
while [ ! -r /dev/usb/hiddev0 ]; do sleep 1; done; \
avrdude -p atmega32u4 -c avr109 -U flash:w:atreus.hex -P
/dev/usb/hiddev0
avrdude: ser_open(): can't set attributes for device "/dev/usb/hiddev0":
Inappropriate ioctl for device
avrdude done. Thank you.
Makefile:143: recipe for target 'upload' failed
Where should I start debugging?
Thanks,
Tyler
