libusb-1.0

[fredycc]

pas-libusb examples compile ok in linux i386 but I have a problem with ARM distribution, specifically: Raspbian: http://www.raspbian.org/. Maybe I have a error in the project configuration.

I do not know if the goal could be this architecture, I appreciate your work.

thanks

Great, I appreciate your testing for ARM very much, thanks!

The logs suggest that the two functions libusb_get_port_number() and libusb_get_port_path() are not available in libusb-1.0. I guess that your distribution uses an older revision of libusb-1.0. Could you please check whether you can update to a newer revision?

Thanks Hansi

[fredycc]

Before test I installed sudo apt-get install libusb-1.0-0-dev, but maybe that distribution uses an older revision, I'll check again.

Thanks Hansi for you fast answer.

Example 1 works compile and works fine in Raspberry, I'll try test the next examples tomorrow. As you indicated the version on Raspberry is old, I downloaded a most recent version from here http://sourceforge.net/projects/libusbx/?source=dlp.

After sh ./configure, make, make install the version created works :). Thank you very much for supporting

Great!

Do you know the version of the libusb-1.0 package of Raspbian? I'd be happy to add a note to the README.

Bye Hansi

[fredycc]

The version that works in Raspbian was 1.0.14 . Thanks

Thanks!

Could you also please tell me, which version was previously installed, which did not work?

Thanks Hansi

[fredycc]

The version that didn't work in Raspbian was 1.0.9.

Version 1.0.14 is not in the repositories of Raspbian actually.

For Linux Mint i386 version: 1.0.12 works

Thanks again for pointing this out! I've added a note to the README.
