I have already reported this as a bug to the HP folks, but I was hoping someone here might have a clue about this one. Just bought an HP Deskjet F2120 and tried to install it on my CentOS 5.064-bit system. The printer installed fine, but sane does not recognize the device, so I tried to install hplip 2.7.10, which is supposed to support it. Installation failed twice - first time because I did not have net-snmp-devel installed. I installed that, then tried again. Now it fails because it claims I do not have libusb installed: INSTALL MISSING REQUIRED DEPENDENCIES ------------------------------------- warning: There are 2 missing REQUIRED dependencies. note: Installation of dependencies requires an active internet connection. warning: Missing REQUIRED dependency: libusb (libusb - USB library) error: This installer cannot install this dependency for your distro/OS and/or version. error: Installation cannot continue without this dependency. Please manually install this dependency and re-run this installer. However, both yum and rpm say this is installed: $ yum list | grep libusb libusb.i386 0.1.12-5.1 installed libusb.x86_64 0.1.12-5.1 installed libusb-devel.i386 0.1.12-5.1 base libusb-devel.x86_64 0.1.12-5.1 base $ rpm -qa | grep libusb libusb-0.1.12-5.1.i386 libusb-0.1.12-5.1.x86_64 I tried installing via the tarball, but it failed, claiming I don't have libjpeg installed (it is, both 32 and 64 bit versions). Note that the hp-check output (below) shows both of these to be installed.... Any/all assistance/guideance would be appreciated - I'd hate to have to pack this up and take it back, but I will if need be. mhr $ hp-check HP Linux Imaging and Printing System (ver. 1.6.7) Dependency/Version Check Utility ver. 2.1 Copyright (c) 2003-6 Hewlett-Packard Development Company, LP This software comes with ABSOLUTELY NO WARRANTY.
