MacBook and USB3

[Antti]

I am a Mac user (OSX 10.8.4 + MacBook Air 5.2).

I have problems with usb3 port. Bladerf-cli works with usb2 cable without any problems. But the usb3 cable comes out the following error.

>bladeRF-cli -p
Backend: libusb
Serial: 3d9eaxxxx
USB Bus: 20

Parallels VM with Ubuntu usb3 works just fine.

What version of libusb are you using? The unsupported speed thing sounds like it might have issues with superspeed and might be a real old version?

I don't have a Mac with USB3, so anyone else who does I would greatly appreciate anyone chiming in on what does or doesn't work.

As for the segfault, we will definitely look into it.

I have a version of 1.0.9 installed via MacPorts.

libusb @1.0.9_0 (active)

[bpadalino]

It looks like superspeed detection for OSX was added in 1.0.15 according to the changelog.

Is there any way to try that version or later out and see if it alleviates your problem?

[Antti]

Now I have the latest version (v1.0.17).

Libraries can be found:
/usr/include/libusb-1.0/libusb.h
and
/usr/lib/libusb-1.0.0.dylib
/usr/lib/libusb-1.0.a
/usr/lib/libusb-1.0.dylib
/usr/lib/libusb-1.0.la

But I get an error:
cmake ../

Any ideas?

[bpadalino]

If you run pkg-config --list-all | grep libusb, what shows up?

Have you tried setting -DLIBUSB_PATH=/usr in your CMake instruction?

[Antti]

Now works. I added libusb-1.0.pc file to "/opt/local/lib/pkgconfig" folder.

Excellent! I'll make a note in the known issues on the wiki.

Thanks for testing!
