There have been hid drivers and general usb drivers in the kernel since 2.6.30. The latest one, hid-multitouch, is a joint effort to unify a set of hid drivers. This will happen in 2.6.39. > The question is very simple. > Where is the correct place in kernel for the multi-touch input support? It depends on your device. If it supports win7 HID extensions for digitizers, adding it to hid-multitouch makes sense. If it is a HID device but it does not quite fit, then it is a new hid driver (which is really discouraged at this point). If it is general usb, then somewhere under drivers/input - there are MT drivers in touchscreen, tablet and mouse. > Sorry for the naive question, but I'm trying to get the difference > between the two. > Any doc available in kernel? Check under Documentation/input/.
