[sane-devel] RE: HP 3970 scanner

Wed, 4 Feb 2004 10:31:31 +0100

Henning, thank you for your feedback.

Could anyone give me some advice to start with this realtek RTS8822L controller? At least a link to their webpage (www.realtek.com is a junk site)

I don't think so. See

See above (link to our contribution page).

I don't know if there are sniffing programs for MacOS.

The above mentioned page says "realtek RTS8822L". Also check if it is
really similar to one of the other HP scanners.

Most scanners can do 48 bit (16 bit per color) inernally. It's used
for color correction internally. Usually you don't need 16 bit
externally but it can make sense if you want to do color correction
after the image has been scanned. E.g. to make a dark image brighter.

It also says that you can use libusb instead.

Use libusb. Your RPM was built with support for libusb most probably
anyway. See man sane-usb for how to set permissions.

If it still doesn't work, send the output of "sane-find-scanner -q"
and "SANE_DEBUG_GT68XX=255 scanimage -L".

Bye,
  Henning

Eddy De Greef very kindly gave me a libsane-gt68xx.so.1.0.13 compiled on a
SuSE environment that uses libusb.  ldd on this showed that it was
compiled with libusb-so.1.0.4  Isn't the supported module libusb-so.1.0.6?

Unfortunately I have libusb-0.1.5.118.  I do have a libusb-0.1.6a-45.i586
but it needs libresmgr-0.1 and I can't find an rpm of this.

I have been through sane-usb and set all the permissions and parameters
appropriately.

I don't have the .usb file and am not sure where I can get it from as the
scanner came without software (I bought it from eBay :( ).

sane-find-scanner -q provides no output at all.

SANE_DEBUG_GT68XX=255 scanimage -L returned the attached output.

If you can advise how I should proceed I would be very grateful.

Cheers,

Jim
