I've also found that in Linux, they > kinda use a special driver to make it work [1]. yes, also I wrote one for NetBSD[1] the mouse itself provides a HID profile but the descriptor does not properly describe the actions of the mouse, and the extra reports are enabled by setting a feature. it should work as a basic mouse with x & y and two buttons though.. although the driver is long, mostly the only bits you need to care about are the input routines and the btmagic_enable() function.

I don't know why it doesn't work but I thought legacy button clicks were built into the normal mouse (did you push? it is not just touch..) middle button and scrolling will not work without a driver though, that is all handled in software.. the mouse itself just reports up to five finger positions, which are stored and compared for each report. after a threshold then scrolling is activated. > I guess I could study how we ourselves handle Synaptics touchpads, but > given this mouse is bluetooth, I figured I better ask here first. I have a tool i wrote to parse the input via a hci sniffer (attached for interest) and another tool which I used to send something to the mouse (i don't remember how that worked, if I had a special driver during development) regards, iain [1] http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/bluetooth/btmagic.c --0-1971321511-1381613931=:523 Content-Type: TEXT/PLAIN; charset=US-ASCII; name=magic.c
