I have Ubuntu 10.04 LTS and need a driver for Driver for HP 3370 digital flatskanner. With earlier Ubuntu versions I could always use this scanner but not now.
Thanks for tips.

Hi,
I found this on the net but am for dumb to understand it:
already the first sentence: unpack SANE driver as root to /usr/lib/sane
I don't get it. Have I to open terminal? Putting in what?
Well - here is the paper I found. Maybe somebody could explain it to me in plain English. Thanks

This is the HP 3770 SANE driver for Linux

Installation:
Installation is manual.
Unpack the hp3770 SANE driver (as root) to /usr/lib/sane:
# cd /
# tar -xvzf /..../hp3770.tgz
Note: /README file left in root directory
Unpack the modified SANE library to /usr/lib/sane:
# cd /
# tar -xvzf /..../libsane.tgz


libsane.so Modification
IF YOU UNPACKED THE MODIFIED SANE LIBRARY ABOVE, YOU CAN SKIP THIS STEP

libsane-hp3770.so is a SANE driver that contains only HP-authored code.
The HP driver contains calls to libsane.so. Unfortunately, libsane.so
lacks the sanei_usb module. To add this module,
1) Obtain the SANE distribution from www.sane-project.org.
2) add "sanei_usb.lo" to the "EXTRA" line in backend/Makefile.in:

diff -e backend/Makefile.in ../sane-backends-1.0.13.hp/backend/Makefile.in
71c
EXTRA = sane_strstatus.lo ../sanei/sanei_init_debug.lo ../sanei/sanei_config.lo ../sanei/sanei_usb.lo
.

3) follow the SANE README build and instructions. This sequence of
instructions appears to install in /etc/sane.d and /usr/lib:
cd sane-backends-1.0.13
configure --prefix=/usr --sysconfdir=/etc
make
su
make install


SANE DLL configuration:
The hp3770 SANE backend will be loaded by the SANE dll by adding "hp3770"
to /etc/sane.d/dll.conf. SANE initializaion is much faster if unneeded
backend modules in dll.conf are commented out.

USB Configuration
The hp3770 SANE backend uses libusb (Linux kernel 2.4.19 and later).
After USB finds the scanner, it should appear somewhere under
/proc/bus/usb. Be sure you have read/write permissions set correctly.
"sane-find-scanner" should find the hp3770 once it is properly connected.

The scanner's device name depends on how USB assigns it. If, for
example, the scanner appears as /proc/bus/usb/001/005, then specify
"hp3770:libusb:001:005" as the SANE device name.
