hi all,
Henning : sorry for my two weeks of silence but I had to work for my
studies.
You will find attached a basic patch for hp2400 scanjet's support in genesys
backend.
Except adding IDs of the scanner in the 'genesys_usb_device_list' array
and
adding a specific 'Genesys_Model' data structure, I don't know what to do.
I compiled the sane distribution (1.0.13) patched with the genesys
backend
and here are various outputs:
"
# sane-find-scanner
# No SCSI scanners found. If you expected something different, make sure
that
# you have loaded a SCSI driver for your SCSI adapter.
# Also you need support for SCSI Generic (sg) in your operating system.
# If using Linux, try "modprobe sg".
found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x0a01 [hp scanjet
scanner]) at libusb:005:002
found USB scanner (vendor=0x06b9 [ALCATEL], product=0x4061 [Speed Touch USB ])
at libusb:003:002
# Your USB scanner was (probably) detected. It may or may not be supported
by
# SANE. Try scanimage -L and read the backend's manpage.
# Scanners connected to the parallel port or other proprietary ports can't
be
# detected by this program.
"
"
# scanimage genesys:libusb:005:002
scanimage: no SANE devices found
"
"
# xscanimage genesys:libusb:005:002
xscanimage: relocation error: /usr/lib/sane/libsane-genesys.so.1: undefined
symbol: sanei_usb_init
"
- Could someone explain me why the 'chip' field doesn't appear in
sane-find-scanner's output ?
- Why the scanimage frontend can't find the device while
sane-find-scanner
could ?
- What's the deal with /usr/lib/sane/libsane-genesys.so.1's symbols ?
Would I
have too agressive CFLAGS ?
thanx for your help, julien
