HPLIP -> HPAIO Error during device I/O

I'm running Chaos Calmer 15.05 (openwrt firmware) in a TPLINK WDR3600 and I'm trying to install SANE + HPLIP in order to get scanner over lan network. I installed sane-libs and sane-daemon + dependencies from official distribuition feed (for Chaos Calmer) and because HPLIP is not available for Chaos Calmer, I had to install HPLIP for 14.07 in third distribuition url , I don't know if the error below is because of this "version", but.... Well... Using sane-find-scanner I get scanner found out by the system, and scanimage -L returns me: > device > `hpaio:/usb/HP_LaserJet_Professional_M1132_MFP?serial=000000000SS17TR2PR1a' > is a Hewlett-Packard HP_LaserJet_Professional_M1132_MFP all-in-one Although scanimage -T returns: > scanimage: open of device > hpaio:/usb/HP_LaserJet_Professional_M1132_MFP?serial=000000000SS17TR2PR1a > failed: Error during device I/O Can someone help me? PS: Sane is returning me error: root@OpenWrt:~# saned -d [saned] main: starting debug mode (level 2) [saned] saned (AF-indep+IPv6) from sane-backends 1.0.25 starting up [saned] do_bindings: bind failed: Address already in use [saned] do_bindings: [1] bind failed: Address already in use [saned] do_bindings: couldn't bind an address.
