LIBUSB_DEBUG = 4 and --enable-debug-log aim at producing the same thing, so, though the non detection is surprising, what's not surprising is that you would get the same issue with either LIBUSB_DEBUG = 4 or --enable-debug-log. > If pcscd is running in foreground mode, everything works fine, no > matter which value (1-4) is assigned to LIBUSB_DEBUG and > "--enabled-debug-log" flag was active or not. Could be a problem with output redirection in pcscd then, rather than a libusbx issue. Considering that no other application has complained about not being able to detect devices when playing with logging, and I have see no evidence that using DEBUG will prevent device detection, I don't think this is a pure libusbx issue. But maybe Ludovic has some ideas. > Note: I always compiled libusbx without the "--enabled-debug-log" flag And you should probably keep it that way, as --enable-debug-log is mostly kept for historical reasons and should only really needed if you want to get a few extra debug messages during init.
