I am running OS X Lion with USB 3 (retina macbook pro). On another computer I updated the firmware on both the radio dongle and the copter, and I confirmed that USB3 works on that other computer. USB3 on the mac says "The IOUSBFamily has successfully enumerated the device"

The problem is in the cfclient. When I run (EDIT: with or without sudo gives same result) the connect window shows only the debug driver. Here is the About Debug Info:

Cfclient version: 2013.4.2
System: darwin

Interface status
debug: Ok
serial: Not implemented
radio: Cannot open Crazyradio. Permission problem? ([Errno None] Unknown error)
udp: Not implemented

Also, the bottom of the window says "Loading device and config" forever, and in the terminal it has this error (I don't know if it is relevant as the program doesn't crash):

I am at a loss for what to do next. No one else seems to have connection problems after the USB3 fix except me. I appreciate any help!

I also tried it in Ubuntu via Parallels and the About Debug Info says this:

Cfclient version: 2013.4.2
System: linux2

Interface status
debug: Ok
serial: Not implemented
radio: Cannot open Crazyradio. Permission problem? (error sending control message: Broken pipe)
udp: Not implemented

In Ubuntu there is no python error so my guess is that isn't relevant after all.

Did you setup the udev rules on your Ubuntu install?

Posted: **Fri May 24, 2013 3:45 pm**

Yes, I did. And after plugging in the USB dongle the lights flash and turn off as they should and dmesg gives this message in Ubuntu:

usb 2-1: new full-speed USB device number 6 using uhci_hcd

Also, when I connect the dongle with parallels open it correctly asks whether to connect it to OS X or Ubuntu. Everything looks fine except the cfclient <-> dongle connection.

Have you tried to run cfclient as root? If you are able to connect then, it may narrow the problem down.

Thanks for the replies. I have tried with and without sudo in both OS X and the Ubuntu VM. The error is the same.

Could you try the latest version (2013.4.2) that is available here. This version contains some extra debugdata that can be seen if you go to Help->About and have a look at the Debug tab. Could you cut and paste the text that's there?

Posted: **Fri May 24, 2013 6:58 pm**

That is the version I have already. I have pasted the debug text above in the 1st and 2nd posts for both OS X and Parallels.

I have solved this issue with a workaround: I bought a USB2 4 port hub and plugged the dongle into that. Now it works fine. I hope this helps any other mac users with only USB3 ports.

So it seems there is still a usb3 problem in the newest firmware for macs? Can anyone confirm this?
