Thanks ! -- that's the solution after doing (2) above. |

I had to run 'iscan-registry --add interpreter usb 0x04b8 0x013b \ |

/usr/lib/iscan/libiscan-plugin-perfection-v550'. |
| 33 |
The whole line is essential & the help file is not very clear, |

As usual with Gentoo, problems are 1 layer deep. |

You have to find the correct item to change, then everything works. |

HTH others who may find it via Google etc. |
