I think this call is needed.

I don't understand: What is it needed for, if the package libusbx including this LIBUSBX_API, is no longer present for years? Since the libusbx project merged back into libusb LIBUSB_API is used instead, so this code-block should be doing nothing as it is no longer called...

This block was detected which function should be called libusb_set_debug or libusb_set_option .
You remove both.

Propose rewrite this ifdef to

#if LIBUSB_API_VERSION < 0x01000106
    libusb_set_debug(slsg->libusb_ctx, LIBUSB_LOG_LEVEL_INFO);
#else
    libusb_set_option(slsg->libusb_ctx, LIBUSB_OPTION_LOG_LEVEL, LIBUSB_LOG_LEVEL_INFO);
#endif

Yes, but that was only if LIBUSBX_API_VERSION was present at all.
A similar call must be present somewhere else, otherwise it would never be called.

We pass the verbosity parameter to functions that open st-link devices.

stlink_t *stlink_open_usb(enum ugly_loglevel verbose, bool reset, char serial[STLINK_SERIAL_MAX_SIZE]);
stlink_t* stlink_v1_open(const int verbose, int reset);

So, I think, somewhere in code we also should set the log level to libusb accordingly.

Edit : Maybe open issue?

Yeah, can you have a look? PR alone would possible do, no need to open a new ticket, I think.

Libusb log level addressed in PR #894.
#endif

slsg->usb_handle = libusb_open_device_with_vid_pid(slsg->libusb_ctx, STLINK_USB_VID_ST, STLINK_USB_PID_STLINK);
if (slsg->usb_handle == NULL) {
WLOG("Failed to find an stlink v1 by VID:PID\n");
