Hi Roman (@maedula),
How did you install libusb?
Could you do a ‘brew info libusb’ …My output looks like the following
His-MBP:~ Ramsin$ brew info libusb
libusb: stable 1.0.21 (bottled), HEAD
Library for USB device access
http://libusb.info
/usr/local/Cellar/libusb/1.0.21 (29 files, 510.5K) *

I’m also on a Mac, and don’t seem to have this issue, though I do have issues updating the firmware using the terminal, I personally think it’s related to LibUSB…though I’m more of a hacker and not an actual programmer to know what to do to resolve the issue, but if I figure anything out, I’ll let you know.
