    Subject[PATCH] [resend] usbtouchscreen: support bigger iNexio touchscreens
    From
    Date
    Bigger Nexio touchscreens not only send more data but also the header values
    are modified somehow. Fix the header somehow (it's a guesswork but it works
    at least on one 46" touchscreen with 2.00SMS firmware) and also increase
    rept_size.
