Those are all normal for running USB on OSX using LIBUSB 0.1.X.
Sometimes you get those errors, and sometimes you don't ... depends on
many parameters, and I've never found a correlation -- though
admittedly I haven't tried very hard ;)
From the printout of "usrp_print_db.py", it looks like your USRP is
correct attached and GNU Radio installed correctly. Yay!

I've looked up other problems, but they seem to be related to libusb
(I have .0.12) or not having usb2 (I'm on a 2nd gen macbook 2).
There doesn't seem to be anything more recent. Anyone have any idea?
I can use things like usrp_fft.py but I always get that message
first. I'd think nothing of it, except that I can't seem to get
radio receiving to work, so I was curious if this could be the reason.
