In this case, the best solution is to provide a driver installer.

Pete's Zadig and the GUI inf-wizard are both based on libwdi. They
will both work for the users. But the better solution is to use libwdi to
generate a driver installer. You may want to take a look at wdi-simple example.
http://git.libusb.org/?p=libwdi.git;a=tree;f=examples

Travis has put up a driver installer using inno-setup.

libusb-win32 has a console install-filter program which can install
the device driver packages as well, but the problem with it is that you
have to use the 64bit install-filter program on 64bit Windows and
the 32bit install-filter program on 32bit Windows.


USAGE: install-filter [install|uninstall|list] <-ac> <-dc> <-ad>
                                               <-c=> <-d=> <-f=>
                                               <-p=> <-w=>

Commands:             Compatible Switches:
  install   (i/-i)      <-ac> <-c=> <-d=> <-f=> <-p=> <-w=>
  uninstall (u/-u)      <-ac> <-c=> <-d=> <-f=> <-p=> <-w=> <-ad>
  list      (l/-l)      <-ac> <-dc> <-c=> <-p=> <-w=>

...

Switches For INF Files:
 --inf=<your_file.inf> (-f=)
    install  : Installs usb device(s) from an inf file.
    uninstall: Attempts to roll back a device driver installation. If
               rollback fails or is unavailable, the device is removed and
               all root hubs are restarted.
