Thanks to both Jack and Olaf for advice. Now all configuration files are in place, except one, sadly being mustek_usb2.conf... Which is just like it was when sane was installed from an rpm package. That's strange, because ./configure clearly says that backend will be built:

However, sane-find-scanner output changed slightly from when i was running it from rpm package. It now only says my scanner is Hewlett Packard when run as root, otherwise it doesn't say anything except vendor, product and chip id: found USB scanner (vendor=0x055f, product=0x0408, chip=SQ113?) at libusb:001:004 --instead of-- found USB scanner (vendor=0x055f [Hewlett-Packard. ], product=0x0408 [USB2.0 Scanner ], chip=SQ113) at libusb:001:004 So i suppose support for BearPaw, even though actually present in sources, should be somehow enabled? How can it be done? P.S. It's maybe offtopic, but i feel very curious. Jack, you are precisely right about my cdma modem, where did you look it up? -- Igor G Novikov <septagramm at gmail.com>
