Exact.

You can use libusb instead of libhal for pcsc-lite (./configure
--disable-libhal). pcscd will then rescan the USB bus every 1 second
to detect reader insertions/removals. I don't know if that will
generate or not traffic on the network for the virtualized USB
connection.

If your virtualized USB connection can generate a udev event for
reader insertion you can configure the CCID driver to support
IFD_GENERATE_HOTPLUG and then avoid the polling every 1 second in
pcscd.
