Multiple USB mouse (trackball) support

I’m writting an application that I’d like to be controlled by two trackballs
(independant of the “main” mouse).

Is this possible? How do I choose the device that I wish to read at any
instant? How do I tell phWindows to ignore those two devices?

Thanks and regards,
Steve

Of course it is possible. But you have to redesign devi-hirun. The last one
sends all input data tp Photon, and there are no way to distinguish the
original data source. Or another idea.: start devi-hirun as a resource
manager (-Pr). There is still one minor problem: in this case only one
device can be created (dev/devi/mouse). However it is easy to fix: just
redesign small part of DDK and invent new command line argument - device
name.
