Issue with libusb 1.0.22 / function 'libusb_set_debug' is deprecated

[LeisureLadi]

Compiling stlink with 'make release' and 'make debug' with libusb 1.0.22 currently throws these warning messages:

Should I revert back to earlier releases of libusb and if so which one?

Thank you,

Hi @LeisureLadi .
I've added PR with a fix. Please check it.

Problem solved! Compiles now without errors. Great.

However, 'libstlink.so.1' was missing initially. I'm not sure, if the libraries are correctly saved in '/usr/local/lib/lib'. I changed the directory name to '/usr/local/lib/stlink' and added this path to '/etc/ld.so.conf.d/libc.conf'. After running 'sudo ldconfig', all is fine now.

Thanks a lot for the quick reply!
Happy Easter!
