Re: [Hp5400backend-devel] Trouble with driver: Segmentation fault

[Lilith <luc...@nt...>]

I deleted the hp5400.conf which was in the folder which I complied and 
installed from, altered hp5400.conf to:

/dev/usb/scanner0
(left 'usb 0x03F0 0x1005' commented out)

Reinstated the info in modules.conf and Xsane is now only detecting one 
scanner now and working nicely with the backend.

Thank you for your help :-)
