It is a rather Bad Hack (seeing as it was built rather blindly to mimic the behaviour of the Windows driver, and has IRQ/port hardcoded in), but it works for me with the 2.2.16 kernel. The device outputs 5 byte packets - 1 status byte, 2 bytes each for X & Y coordinates. The devel branch of GTK+ has support for /dev/fidmour in the Linux framebuffer backend (gtk+/gdk/linux-fb/gdkmouse-fb.c), should you wish to see a code sample. I'm wondering if anyone has a resource that would provide information on porting this driver to the 2.4 kernel. I would welcome comments on this driver, or on the MPC-501 and Linux in general. Bonus points to anyone who actually understands why the driver works and how the hardware works. :) Hope this helps, -- Elliot Who me?
