hi,
I recently got a good usb mouse (logitech mx 510), that I intend to use in usb mode and I am considering writing a proper driver for linux. After some investigations I think I have a clear idea about current state of usb mouse support in linux.
it seems that new/full hid input driver is about the same in 2.4.x and 2.6.x and it still uses usb mice in boot protocol.
there isn't much support for parsing arbitrary hid report descriptors (?)
nor for compiling downstream reports (not needed here).
What I think I have to do is basically the following: * grab the particular usb device so that generic hid driver skips it * register with the input core * set the device to the report protocol * understand the report descriptor * parsing the reports * send events to the input core * be prepared to device disconnect when the driver is unloaded: * reset the device back to boot protocol * release the device * release the input core association
Anything I got wrong? Any other ideas or pointers?
Cheers, dima
