interestingly to note: I have the exact same system (12-CURRENT r314251 and with same ports
from my own pkg repository out of poudriere) in a VBOX machine; when I start there the pcscd
in foreground and with --debug it says:


root at r314251-amd64:~ # /usr/local/sbin/pcscd --debug --foreground
00000000 pcscdaemon.c:346:main() pcscd set to foreground with debug send to stdout
00000516 configfile.l:358:DBGetReaderList() Parsing conf file: /usr/local/etc/reader.conf.d
00000043 pcscdaemon.c:655:main() pcsc-lite 1.8.20 daemon ready.
00010018 hotplug_libusb.c:440:HPEstablishUSBNotifications() Driver ifd-ccid.bundle does not support IFD_GENERATE_HOTPLUG. Using active polling instead.
00000124 hotplug_libusb.c:449:HPEstablishUSBNotifications() Polling forced every 1 second(s)

and a truss on the PID shows that is is really polling once every second:

...
openat(AT_FDCWD,"/dev/ugen1.1",O_RDWR,00)	 = 7 (0x7)
openat(AT_FDCWD,"/dev/ugen1.1",O_RDWR,00)	 = 8 (0x8)
ioctl(8,USB_GET_PLUGTIME,0xdfdfcddc)		 = 0 (0x0)
ioctl(7,USB_GET_CONFIG,0xdfdfce44)		 = 0 (0x0)
close(8)					 = 0 (0x0)
close(7)					 = 0 (0x0)
openat(AT_FDCWD,"/dev/ugen1.1",O_RDWR,00)	 = 7 (0x7)
openat(AT_FDCWD,"/dev/ugen1.1",O_RDWR,00)	 = 8 (0x8)
...

On the other system, an Acer C720 netbook, it says only:

root at c720-r314251:~ # /usr/local/sbin/pcscd --debug --foreground
00000000 pcscdaemon.c:346:main() pcscd set to foreground with debug send to stdout
00000550 configfile.l:358:DBGetReaderList() Parsing conf file: /usr/local/etc/reader.conf.d
00000049 pcscdaemon.c:655:main() pcsc-lite 1.8.20 daemon ready.

i.e. the line about hotplug_libusb.c:440:HPEstablishUSBNotifications()
does not show up; and a truss shows that is is doing/waiting on
something on a dev; it is very slow doing some ioctls:

openat(AT_FDCWD,"/dev/usbctl",O_RDONLY,00)	 = 11 (0xb)
ioctl(11,USB_READ_DIR,0xdfdfcb38)		 = 0 (0x0)
openat(AT_FDCWD,"/dev/ugen1.1",O_RDWR,00)	 = 12 (0xc)
ioctl(12,USB_GET_PLUGTIME,0xdfdfcb1c)		 = 0 (0x0)
ioctl(12,USB_GET_DEVICE_DESC,0xdfdfcb20)	 = 0 (0x0)
ioctl(12,USB_GET_DEVICEINFO,0xdfdfccb0)		 = 0 (0x0)
