I removed the PCMCIA reader, restarted pcscd, plugged in 1 CCID reader.
After unplugging the device, no other USB device insertion is detected by pcscd.
I tried this with both the ACS ACR 38 and the SCM SCR 3310.
So the problem even occurs when only 1 reader is attached and removed.
I think there's an issue with my hotplug/udev configuration ?

After un plugging the ACS reader:
