   * rx_tasklet is now a parameter of the module xpp, rather than of xpp_usb.
   * New FPGA firmware: 5128 (1151) / 5122 (1141, 1131):
     - Fixes synchronization issues.

   * perl module and utilities:
     - Modules no longer magically scan system on initialization.
     - Scanning is by calling explicit methods.
