Comment 16 for bug 132781

It happened to me too, psc 1210 detected, but couldn't be opened. So i went to hplip's homepage and downloaded the latest version. While installing, this came up:

INSTALL MISSING REQUIRED DEPENDENCIES
-------------------------------------
warning: There are 3 missing REQUIRED dependencies.
note: Installation of dependencies requires an active internet connection.
warning: Missing REQUIRED dependency: python-devel (python-devel - Python development files)
warning: Missing REQUIRED dependency: libusb (libusb - USB library)
warning: Missing REQUIRED dependency: libtool (libtool - Library building support services)

INSTALL MISSING OPTIONAL DEPENDENCIES
-------------------------------------
warning: There are 5 missing OPTIONAL dependencies.
note: Installation of dependencies requires an active internet connection.
warning: Missing REQUIRED dependency for option 'network': libcrypto (libcrypto - OpenSSL cryptographic library)
warning: Missing REQUIRED dependency for option 'network': libnetsnmp-devel (libnetsnmp-devel - SNMP networking library development files)
warning: Missing OPTIONAL dependency for option 'fax': reportlab (Reportlab - PDF library for Python)
warning: Missing REQUIRED dependency for option 'scan': sane-devel (SANE - Scanning library development files)
warning: Missing OPTIONAL dependency for option 'scan': scanimage (scanimage - Shell scanning program)

So, regarding the libusb, there are 2 possibilities: or it's in a non-usual place or it wasn't installed....
