libhpmud-dev 3.10.2-1ubuntu5 (sparc binary) in ubuntu lucid

 Shared library that provides direct I/O for each process. Prior to
 hpmud, all I/O was serialized through hpiod, a monolithic I/O processor.
 The new hpmud direct I/O is faster. Hpmud supports parallel, USB and
 JetDirect connectivity.
 .
 With hpmud, HPLIP no longer has Linux specific libusb extensions. This
 means any UNIX/Linux derivative that supports libusb may work with
 HPLIP. A public HPLIP "C" API is exposed through hpmud. See hpmud.h
 for documentation. A Python wrapper for hpmud, called hpmudext, is also
 available.
