I'm using the latest git-mainline version of libusbx on all machines, with the extra debugging output you advised me to include. The only difference between test and prod is the LIBUSB_DEBUG level (2 on prod/4 on test).

Perhaps, you don't have to do anything like that. I did some additional tests regarding the non-logging of error messages on the prod machines. The result: pcscd is logging the libusbx messages (stdout/stderr) ONLY in foreground mode. On the prod machines pcscd is not running in foreground mode, but on test. That's why we got the timerfd warning message in the log file there. So I decided to modify libusb/core.c to redirect any messages to the syslog facility, instead of writing to stderr. (Note: I was against this modification in the first place because of the risk of adding additional errors.) Finally, I'm able to provide you the following error message: libusbx: warning [add_to_flying_list] failed to arm first timerfd (errno 22, it_value = 259823:1000000000) From [1]: Errors EINVAL new_value is not properly initialized (one of the tv_nsec falls outside the range zero to 999,999,999).
