Well, there's no errno 13 in it.
However, what is remarkable compared to my trace file is
open("/System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBLib.bundle/Contents/MacOS/IOUSBLib\0",
0x0, 0x1FF) = 3 0
It uses IOUSBFamily.kext rather than
open("/System/Library/Extensions/IOHIDFamily.kext/Contents/PlugIns/IOHIDLib.plugin/Contents/MacOS/IOHIDLib\0",
0x0, 0x0) = 3 0
IOHIDFamily.kext.
That despite of your configuration claiming successfully finding
hidapi. That might explain these "Cannot claim interface" errors, but
the question is why it doesn't use hidapi.
The respective code is:
#if defined(HAVE_LIBHIDAPI)
/*
* Try HIDAPI first. LibUSB is more generic, but might then cause
* troubles for HID-class devices in some OSes (like Windows).
*/
serdev = &usbhid_serdev;
for (usbpid = lfirst(pgm->usbpid); rv < 0 && usbpid != NULL; usbpid =
lnext(usbpid)) {
pinfo.usbinfo.flags = PINFO_FL_SILENT;
pinfo.usbinfo.pid = *(int *)(ldata(usbpid));
pgm->fd.usb.max_xfer = USBDEV_MAX_XFER_3;
pgm->fd.usb.rep = USBDEV_BULK_EP_READ_3;
pgm->fd.usb.wep = USBDEV_BULK_EP_WRITE_3;
pgm->fd.usb.eep = 0;
strcpy(pgm->port, port);
rv = serial_open(port, pinfo, &pgm->fd);
}
if (rv < 0) {
#endif /* HAVE_LIBHIDAPI */
#if defined(HAVE_LIBUSB)
serdev = &usb_serdev_frame;
for (usbpid = lfirst(pgm->usbpid); rv < 0 && usbpid != NULL; usbpid =
lnext(usbpid)) {
...and then, it proceeds to using libusb.
What you could do now:
* verify in ac_cfg.h HAVE_LIBHIDAPI is actually set
* add some debug fprintf(stderr ...) statements above to see
whether hidapi actually finds something
Since you already specified -vvv, usbhid_open() would have logged a
"No devices found" in case of failure. However, your messages say it's
going straight to usbdev_open() which is the libusb counterpart.
So, to me, it seems for some reason, Brew's hidapi library might be
the problem here, even though it's been found by configure.
