Yes, with recent versions of pcsc-lite it doesn't. But the version shipped with e.g. Ubuntu 9.04 only works if the driver is able to handle a device name using the libHAL scheme. It doesn't try again with the libusb path (which, granted, later versions do).

[...] As a driver maintainer I know that of course ;-) but that only holds for more recent versions of pcsc-lite (as described above). But unfortunately we also have to support Linux distributions even as old as Ubuntu 9.04 ;-) The constant changing of hotplugging in Linux in fact *does* influence the driver since it has to implementent the predominant naming scheme used by pcsc-lite. I really appreciate that current versions of pcsc-lite try again initializing the driver with a different naming scheme (e.g. "libusb:") if the driver doesn't support the "libhal:" name, but that's something you added later.
