If you do not want to set a serial number then do not use it at all. _Many_ smart card readers do not have a USB serial number, with no problem I know of. If your devise has a USB serial number it will be displayed in the PC/SC name by pcsc-lite. The PC/SC reader name will be something like: "Crypto Stick (serial) 00 00". So if your serial number is meaningless and always 00000 I suggest to just remove it.
