Nothing but trouble with AVR-ISP-MKII on latest OS X

I recently purchased an Olimex AVR-ISP-MKII from Mouser to program an ATMega 644P for a project I'm working on. I'm running on the latest OS X (10.10.3 at the time of this post) and flashing the chip with avrdude. The first hurdle was the bug mentioned here https://www.olimex.com/forum/index.php?topic=3208.0. Turns out that a year later it still is not fixed. Therefore I'm using avrdude 5.11 instead of 6.0.1. I have the updated firmware on my AVR-ISP-MKII so that I can use avrdude.

The basic output I'm receiving from avrdude is as follows:


⊗ /src/avrisp-testing/testbed/bin/avrdude -c avrispmkii -p m644p -P usb

avrdude: stk500v2_command(): command failed
avrdude: stk500v2_program_enable(): bad AVRISPmkII connection status: Unknown status 0x00
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.


avrdude done.  Thank you.


For the super verbose output see here https://gist.github.com/joefiorini/2154e370dcfc858e34c5.

To rule out problems with my project, I'm testing this on an Arduino Uno R3 (ATMega 328P). I have verified the pin outs of both the 10-pin ICSP and the ICSP on the Arduino board, and everything seems to be correct. The LEDs on the board light up, indicating I have power. Everything seems to be setup correctly yet avrdude refuses to connect to any MCUs through the programmer. At this point I can't see any other answer than a problem with my computer or my programmer. I have no clue what to try next, though. Any thoughts on where I can go next?

Thanks!
