Previously I had selected 4 items from the list in SANE_BACKENDS, which is shown by 'emerge', ie 'epson epson2 plustek plustek_pp'. My scanner is an 'Epson V550 Photo'. Wanting to test which of the 4 items above was needed, I tried each. Inadvertently, I tried emerging 'sane-backends' with none included & discovered that my scanner still works regardless ! There is a file /etc/hotplug/usb/libsane.usermap , which lists scanners, & I have the line under 'V550' enabled. What is the purpose of the long list of SANE_BACKENDS, if Xsane finds the correct driver with none enabled ? -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
