usb.core.USBError: [Errno 13] Access denied (insufficient permissions)

Hello,
I'm getting this error whilst trying to run any command in OS X (Mavericks 10.9.5), even running it as root... does not seem to work, cheers

Same here, found nothing online that helps...

I am having the same issue on OS X 10.10.3 (Yosemite).

Same problem, any clue ?

I haven't managed to duplicate this as we're running the code on a Raspberry Pi and Windows, and I've only tested on an older Mac. I did come across this thread that seemed related:

Yubico/python-yubico#7

If you drop pyusb and libusb and use hidapi this works perfect.

Just install hidapi: pip install hidapi

And replace pyusb references with:

import hid

hidraw = hid.device(0x2123, 0x1010)
hidraw.open(0x2123, 0x1010)
hidraw.send_feature_report([0x02, 0x10, 0x00,0x00,0x00,0x00,0x00,0x00])

The above code will connect to the device and send a fire command.

Thanks, closing this now, I don't even have it now :)
