You find in genesys_devices.c at the end a block of lines:
static Genesys_USB_Device_Entry genesys_usb_device_list[] = {
  {0x0638, 0x0a10, &umax_astra_4500_model},
  {0x04a9, 0x2213, &canon_lide_50_model},
  {0x04a9, 0x221c, &canon_lide_60_model},
  {0x04a9, 0x221f, &canon_lide_500f_model},
  {0x03f0, 0x0901, &hp2300c_model},
  {0x03f0, 0x0a01, &hp2400c_model},
  {0x03f0, 0x1405, &hp3670c_model},
  {0x07b3, 0x0600, &plustek_st12_model},
  {0x07b3, 0x0601, &plustek_st24_model},
  {0x0461, 0x0377, &medion_md5345_model},
  {0, 0, NULL}
};

Here you have to add your scanner.

Another block, which defines the model, is also necessary.
After this recompile and reinstall the backends.

I've done the same with canon_lide_500f_model - and Pierre Willenbrock
gave usefull hints.

Now I have made a table with the differences between the register settings
between Windows and Sane on
http://www-user.tu-chemnitz.de/~sontag/sane/
- but the scanner still not works ...
