Re: usb-scanner detected, but nothing about usb in /dev

[Paul Lewis <paul.lewis@karachi.freeuk.com>]

Have you got your scanner working yet?

I have just managed to get my HP scanner working within the last hour. 
The only serious thing I needed to do was edit two files in /etc/sane.d

The first was dll.conf where I rem'd out all the entries except net and 
hp
the second was hp.conf where I made a minor change for it to read

/dev/usb/scanner0
option connect-device

Checking first that there was a scanner0 in /dev/usb, which there was.

That was it - then xscanimage worked a treat. Sane-find-scanner gave 
similar errors to those you experienced.

Regards
