Just for the record, I tested the R-box to the maximum range of my know-how and couldn't get the USBtoUART Bridge driver to recognize it on my late-2012 Macbook Pro (running 10.9.2 Mavs)...
No matter which versions of bfgminer/cgminer I compiled, regardless of which specialized drivers I subbed in (even tried subbing and integrating drivers between bfgminer and cgminer), and irrespective of which parts of the codes I manually forked, the device wouldn't appear anywhere on the system, let alone in cgminer. I've been mining with Bitmain's U2's on said Mac for weeks, so the UART bridge definitely works on Mavericks.
Now, I'm no coding whiz, but I know my way around a few different languages and at this point can read luke's code better than I'm able to read in Spanish (6 years academic). However, the box works with remarkable ease on both my Lenovo Carbon X1 Thinkpad and Lenovo Yoga 2.
Are they just not programmed to interface with OSX? Am I just doing the proverbial
it wrong by trying to mine through a Mac? The reason I ask is that after testing with the U2's it seemed to output more consistent overclock voltage to the chips (arranged in series via a Kanex 3.0 hub). Granted, this doesn't matter, as the R-box uses a separate PSU, but still, it'd be nice to have at least one of my laptops for something other than mining room decor.
Definitely open to any comments/suggestions. Like I said, I've got everything running on a Lenovo right now, but cross-system compatibility is always reassuring.
ok lets try.
