This package provides an interface to the SONY Reader PRS-500 over USB.

The public interface for device backends is defined in libprs500.device.
  
There is also a script L{prs500} that provides a command-line interface to 
the SONY Reader. See the script
for more usage examples. A GUI is available via the command prs500-gui.

The packet structure used by the SONY Reader USB protocol is defined 
in the module L{prstypes}. The communication logic
is defined in the module L{communicate}.

In order to use it as a non-root user on Linux, you should have 
the following rule in C{/etc/udev/rules.d/90-local.rules} ::
  BUS=="usb", SYSFS{idProduct}=="029b", SYSFS{idVendor}=="054c", 
  MODE="660", GROUP="plugdev"
You may have to adjust the GROUP and the location of the rules file to 
suit your distribution.
