Another set of USB vendor ID's... this time, vendors weren't described. The
same comment I did on patch 2/3 applies here... IMO, we should really try
to create a global list of vendors/devices on kernel. Of course this is not
a non-go issue, as it is already present on several other USB drivers.

Before digging into all code details, am I wrong or this device has the
pulse/space decoding inside the chip?

In this case, we shouldn't really be converting their IR keystroke events into
a pseudo set of pulse/space marks, but use the standard events interface.

Cheers,
Mauro.
