These receivers just pass IR pulses to a serial control pin (e.g., DCD) and rely on the lirc_serial driver to receive all signal transitions with precise timing (in microseconds); this won't work over USB. So you need to find an USB IR receiver which is supported by LIRC. Another option is to get a PCI (or PCI-Express) serial port card - it might work with lirc_serial, if it is compatible with 16550 and uses IO port mapping (some of these devices are using memory-mapped registers - they won't work without code changes in lirc_serial). However, such configuration is not supported by lirc_serial directly (in particular, lirc_serial wants to get IO port address in its module parameters, and addresses for PCI devices are dynamic and may change between boots).
