make says libusb_get_port_path is deprecated

[hudsantos]

Hello,

I've compiled in a Linux Mint 17, it generated binary and worked fine, but:

# make
cc -g -O0 -Wall -Wextra uhubctl.c -o uhubctl -Wl,-z,relro -lusb-1.0
uhubctl.c: In function ‘usb_find_hubs’:
uhubctl.c:345:17: warning: ‘libusb_get_port_path’ is deprecated (declared at /usr/include/libusb-1.0/libusb.h:1358): Use libusb_get_port_numbers instead [-Wdeprecated-declarations]
                 int pcount = libusb_get_port_path(NULL, dev, port_numbers, MAX_HUB_CHAIN);

worked fine I mean it has compiled and executed... but it seems the hardware where I tried to run it is not compatible:

Intel Corporation 82801H (ICH8 Family) USB UHCI Controller

Can you​ check what is the value for LIBUSB_API_VERSION on your system? Perhaps grep for it under /use/include/libusb-1.0. There is ifdef that should use new way to get that information, but it depends on a value of LIBUSB_API_VERSION.

As for supporting particular hardware, it's tough call. Very few USB hubs support PPPS (per port power switching) properly, and I am trying to keep compatibility list current. If you find hardware that works, please report!

Hi,

Thanks for replying. Sure I'll let you know if I found hardware that works.

$ grep -Ri API_VERSION /usr/include/libusb-1.0/

Hmm. uhubctl is looking for LIBUSB_API_VERSION here. However, on your system, not only you don't have this macro LIBUSB_API_VERSION defined, but even non-compliant `LIBUSBX_API_VERSION is not defined either, just mentioned in comments?

Do you know which version of libusb you have installed on your Linux Mint?
libusb 1.0.16 or later must have LIBUSB_API_VERSION defined, otherwise it cannot be called libusb.

dpkg says I have this version:
ii libusb-1.0-0:amd64 2:1.0.17-1ubuntu2 amd64 userspace USB programming library

I'll take a look. Seems clearly this is not a issue with your code.
Even so I appreciate very much your help bro. I'll apt-get update/upgrade/dist-upgrade everything here..
Hope this will solve the problem.

I hope community keeps valuing your work!
