Maybe something like the way gpm works? There is no API I am aware of for this sort of stuff, so you can just dump it out as a two element struct (with some kind of magic sync number as well, maybe). In the USB model, I just do the control transfer directly from the display application. I am interested in how you end up implementing this - I'm working on a kcontrol applet for KDE that shows the channel and battery power, and it'd be cool to support this as well.

Re: Getting additional info from an XInput driver
Xinput isn't prepared to handle these very device dependent informations very well. I have a new xf86misc extension in mind which can be used to configure device dependent parameters and retreive device dependent information from devices. Unfortunately I have been side tracked too much lately that I didn't have time to look into this. Once this extension is in place it may be used to reteive this information. I'm writing about PS/2 mice, not USB. And the info is there, have a look here: http://www.dqcs.com/logitech/PS2ppSpec.htm and I have no problem retrieving it, for example using this simple patch over mouse.c: @@ -1416,6 +1416,9 @@ dw = (pBuf[2] 0x08) ? (pBuf[2] 0x0f) - 16 : (pBuf[2] 0x0f); break; +case 5: /* wireless status type packet */ +xf86Msg(X_INFO, %s: battery level: %d, RF channel: %d\n, pInfo-name, + pBuf[2] 0x07, (pBuf[2] 3) 0x07); case 0: /* device type packet - shouldn't happen */ default: buttons |= (pMse-lastButtons ~0x07); (I have Logitech Cordless MouseMan Optical). What the problem is is getting the info from the driver to a client (once it has been read from the mouse). Does this mouse use the Mouseman+ protocol? We can add something like this to the driver but we may have to add a new mouse type for the Logitech mice as these bits may code something else on another (non-Logitech) mouse or is this an 'official' extension of the Mouseman+ protocol?

Re: Getting additional info from an XInput driver
I'm not sure Xinput really supports this sort of functionality right now. Support for this may be something for 5.0.
